    This paper reports the voltage unbalance compensation performance of a three-phase inverter for a Voltage Unbalance Compensator (VUC) controlled by using the method of symmetrical components for an induction motor. The VUC consists of a three-phase PWM rectifier, a DC-link capacitor, and an inverter. The rectifier is connected to the power grid lines and the inverter is connected to one of the ends of the open-winding induction motor. It supplies compensating voltage and keeps the terminal voltage balanced of the induction motor when the voltage unbalances occur on the power grid. By using the method of symmetrical components, the unbalanced three-phase voltage can be represented by a combination of balanced three-phase voltages. Therefore, the compensation voltage can be easily controlled. We clarified that the voltage performance of the inverter for the VUC by simulation and experiment. The results showed that the proposed VUC suppressed the voltage unbalance.

    This paper shows the current and torque performance of a 750 W induction motor with a voltage unbalance compensator (VUC) when a DC link voltage is boosted using simulation. The VUC consists of a diode bridge, an inverter, and a voltage booster, however, DC voltage source was used in the simulation simply instead of the diode bridge and voltage booster. The VUC is connected to both of the power grid lines and the induction motor windings. It supplies compensating voltage and keep the terminal voltage balanced of the induction motor when the voltage unbalances occur on the power grid. It was cleared that the compensable range was expanded by boosting the DC link voltage of the VUC in the simulation. Besides, pulsation torque was also suppressed by voltage compensation enhancement. The current and torque waveforms were compered under three conditions such as without the VUC, with the VUC without boosted voltage, and with the VUC with boosted voltage. As a result, we clarified that the current and torque performance of the induction motor with the VUC is improved by the voltage booster even if the voltage unbalances factor increases.

This paper deals with the thermal resistance and thermal conduction characteristics of a Nickel Micro Plating Bonding (NMPB) power module in comparison with those of a power module adapting a conventional structure with a high-temperature solder attachment. An attempt is made to estimate the thermal resistance and thermal structure function for the two types of power modules when peeling of the chip junction occurs. In terms of spreading heat, an NMPB is superior to a conventional power module using high temperature solder, because NMPB allows spreading heat from both sides of the chip and setting the heat spreader near the chip.

    © 2019 IEEE. This paper introduces a new means of operating an induction machine which utilizes a relatively small converter circuit that is capable of maintaining balanced conditions within the machine even during periods of a voltage unbalance in its AC supply, The control method required for satisfactory operation of the circuit is described and the validity of the control method is confirmed by simulation. Finally, it is shown by experiment that the technique allows one to maintain the performance of the induction machine for both sudden voltage sag and voltage surge conditions. This proposed approach is expected to solve persistent problems such as over current, local heating, vibration and stalling when an unbalance voltage occurs.

    © 2017 IEEE. Aiming for application to the inverter system of HEV and EV, we have developed a novel packaging technique for SiC power devices based on Nickel Micro Plating Bonding (NMPB) technique. We implemented heat resistant mounting of SiC schottky barrier diode (SBD) on the TO247 type package and confirmed the rectifying behavior even after the high temperature storage for 500hr at 250°C without any significant degradations. We also fabricated one-leg inverter modules mounting SBDs and MOSFETs using newly designed lead frames for NMPB process. The module showed normal rectifying and switching behavior even at high temperature such as about 250°C.

This paper deal with structure for low inductance and high heat operation of silicon carbide (SiC) power module, which attracts attention in terms of high withstand voltage, high efficiency and high heat operation in recent years. First, the parasitic inductance of the power module of two types of structure; a conventional structure which forms the current path in a planar manner and a structure formed three-dimensionally is investigated using electromagnetic field analysis. In addition, thermal resistance of two types of power modules are experimentally evaluated from heat radiation performance. Experimental and simulated results reveals that the three-dimensionally formed power module is superior in the current path, resulting in lower parasitic inductance as well as smaller switching loss. Moreover, on state resistance and leakage current are evaluated at the junction temperature of 250 °C and the problems of power module package under high temperature environment is also investigated.

    © 2017 Wiley Periodicals, Inc. In this paper, a driving method for an interior permanent magnet (IPM) motor is proposed; this method increases the system efficiency in the constant power region. In the driving method, the pulse width modulation inverter with a voltage booster system allows the use of both flux weakening control (FWC) and dc link voltage control (DVC) to drive an IPM motor at high speed. The authors investigate how a combination of FWC and DVC is suitable for the system. First, a simulation model is introduced. This model allows the calculation of the system efficiency and each part of the system losses in the voltage booster, inverter, and IPM motor. Furthermore, the system efficiency is calculated using the simulation model, and the simulation results are discussed when the ratio between the FWC and the DVC is changed. The IPM motor drive method is expected to help achievement of high efficiency by adjusting the ratio between the two control methods in the constant power region.

    © 2016 IEEE. This paper deals with a developed system that allows to drive an induction motor and charge a battery using wireless power transfer (WPT) for automated guided vehicle (AGV). The developed system enables to control output voltage of WPT by constantly moving the receiving coil and adjusting the gap length. It is desired that the system should withstand high voltage, and reduce copper loss and conduction loss in coil and power conversion circuits, respectively, to achieve high efficiency for the system. However, methods for determining the output voltage in the WPT system for AGVs has not been investigated yet. From the viewpoints, we investigate the allowable maximum output voltage provided by the developed WPT system. The maximum voltage is calculated using control equations including parameters of voltage booster, power supply voltage and battery current when the battery current control is adopted. Furthermore, experimental results reveal that the battery current control cannot be used beyond a maximum DC link voltage. In addition, a properly selected gap length of the coil is found to allow an induction motor to be driven and the battery to be charged using the WPT system. As a result, it is clarified by the experiments that the developed control system provides additively effective function to WPT for AGVs.

    © 2015 IEEE.In recent years, the introduction of contactless power transfer (CPT) system is required to automated guided vehicle (AGV) used in a factory. This paper deals with development of prototype contactless power transfer system for applying to AGV using both experiment and simulation. It is found that the developed prototype contactless power transfer system allows 1 kW power transfer in more than 68% of power transfer efficiency at 20 mm gap. Furthermore, an attempt is made to optimize the CPT by changing the core shape of the coils. As a result, combination of T-T shape cores made of ferrite core allows transmission of more power than T-E combination cores. These results suggest that the T-T shape cores contribute to further miniaturization of CPT system and larger capacity than previous CPT system using T-E combination cores.

    © 2015 IEEE.This paper deals with investigation on electrical characteristics of both conventional Si-IGBT and next generation power semiconductor device SiC-MOSFET for high efficiency inverter of contactless power transfer system. This system has an issue that the power conversion efficiency is lower than that of conventional charging system using a plug. Since a proto type contactless power transfer system that we evaluated before adopted Si-IGBT, higher power conversion efficiency has been required. Thus, an attempt is made to improve the inverter efficiency using SiC-MOSFET. The performance of Si-IGBT and SiC-MOSFET are evaluated by conducting a switching test and experiment of static characteristics. Furthermore, inverter loss is calculated and discussed using experimental results of Si-IGBT and SiC-MOSFET. As a result, the inverter efficiency is found to increase by 0.48% using SiC-MOSFET. Additionally, it is suggested that ringing of the voltage and current should be suppressed when SiC-MOSFET is applied to an inverter for high frequency application like a contactless power transfer system.

    In this paper, authors investigate calculation method of losses in system which consists of interior permanent magnet (IPM) motor and PWM inverter with voltage booster. This system has two driving methods for motor in high speed region. One is DC link voltage Control. The other is flux weakening control. However, it is not cleared how combination of these two control methods is suitable for this system. It is necessary to quantitatively estimate parts of system losses in voltage booster, inverter and IPM motor, because total efficiency of system is decided by parts of system losses. So, the simulation model, which is capable of calculating parts of system losses to find suitable driving method for IPM motor using combination of the two control methods, is introduced and simulation results are discussed. © 2014 IEEE.

    The purpose of our work is to develop a power module using gas insulation and bonding-less interconnections to avoid the reliability issues known to current packaging technology. This paper deals with the temperature dependence of partial discharge inception voltage (PDIV) of a developed module up to 300 °C. In addition, an attempt is achieved to confirm half-wave rectifying operation up to 300 °C using SiCSchottky barrier diodes (SiC-SBD). From these results, the PDs were not detected up to 1500 V and 300 °C, proving its ability to be used in high temperature applications. © 2014 The Institute of Electrical Engineers, Japan.

    An interior permanent magnet (IPM) motor drive system which has regenerating capability augmented by electric double-layer capacitors (EDLCs) is proposed. In the proposed system, EDLCs are arranged in series with batteries so that a lesser number of the EDLCs and batteries will be required. The proposed system has two bi-directional voltage boosters: one is for both the batteries and EDLCs to control the dc-link voltage of a PWM inverter and the other is for only the EDLCs and is used to control the energy flow from and to the EDLCs. In this paper, a strategy to control the energy flow to and from the EDLCs is explained and its effectiveness is confirmed by simulation and experimental results. Furthermore, the efficiencies of the voltage booster, inverter, PM motor, and whole system are measured for the system with the basic configuration, i.e., which consists of only one bi-directional voltage booster and PWM inverter. Then, the steady-state characteristics are determined. Finally, the efficiency of the voltage boosters in the proposed system is determined, and the advantage of the proposed PM motor drive system is discussed. © 2011 The Institute of Electrical Engineers of Japan.
