  • A Condition-Monitoring Method of DC-Link Capacitors Used in a High-Power Three-Phase PWM Inverter with an Evaluation Circuit

    Hasegawa Kazunori, Nishizawa Shin-ichi, Omura Ichiro

    IEEJ Journal of Industry Applications    8 ( 3 ) 480 - 487   2019年01月  [査読有り]

     概要を見る

    <p>This paper presents a condition-monitoring method of dc-link capacitors used in a high-power three-phase PWM inverter with an evaluation circuit intended for ageing tests. Although its power rating is 1/25 of the inverter, the evaluation circuit provides the equivalent ripple current waveform and dc-bias voltage to the high-power inverter. The monitoring method independently extracts the capacitance and ESR of the dc-link capacitor, where the fast Fourier transform is introduced to the ripple current waveform and the dc-link voltage of the evaluation circuit. Experimental results verify that the monitoring method obtains both the ESR and capacitance changes of a capacitor under test.</p>

  • Calorimetric Power-Loss Measurement of a High-Power Film Capacitor with Actual Ripple Current Generated by a PWM Inverter

    Hasegawa K., Omura I.

    2018 IEEE Energy Conversion Congress and Exposition, ECCE 2018      4688 - 4691   2018年12月  [査読有り]

     概要を見る

    © 2018 IEEE. This paper proposes a calorimetric power-loss measurement method suitable for a high-power film capacitor used in the dc link of a high-power three-phase PWM inverter. The measurement method is characterized by using a thermally-insulated container and an evaluation circuit for dc-link capacitors. Introduction of the thermally-insulated container achieves an accurate power loss measurement that is of the order of 1 W. The evaluation circuit provides the equivalent ripple current waveform and dc-bias voltage to those of the high-power three-phase PWM inverter although its power rating is 1/24 of the high-power inverter. This combination makes it possible to measure the power loss of the capacitor under actual voltage/current condition at low cost. Experimental results obtained from a 1200-V 210-kVA system verify the viability and effectiveness of the proposed method.

  • An Evaluation Circuit for DC-Link Capacitors Used in a High-Power Three-Phase Inverter with Condition Monitoring

    2018 International Power Electronics Conference, IPEC-Niigata - ECCE Asia 2018      1938 - 1942   2018年10月  [査読有り]  [招待有り]

     概要を見る

    © 2018 IEEJ Industry Application Society. This paper presents a condition monitoring method of dc-link capacitors used in a high-power three-phase PWM inverter intended for load life testing with an evaluation circuit consisting a low-voltage inverter. The evaluation circuit provides the equivalent ripple current waveform and dc-bias voltage to those of the high-power inverter. Hence, the monitoring method allows the load life testing with the equivalent condition to the high-power inverter at low cost. Experimental results verify that the monitoring method extracts both the ESR and capacitance changes of a capacitor under test.

  • Bias voltage criteria of gate shielding effect for protecting IGBTs from shoot-through phenomena

    Tsukuda M., Abe S., Hasegawa K., Ninomiya T., Omura I.

    Microelectronics Reliability    88-90   482 - 485   2018年09月  [査読有り]

     概要を見る

    © 2018 Elsevier Ltd In this paper, we propose the criteria of bias voltage from parasitic capacitance and demonstrate the criteria in an experiment with the present IGBT. The bias voltage criteria are theoretically predicted for the new generation IGBT based on the scaling principle. For safe switching, the required gate voltage bias is predicted to be −1.2 V or less for the present IGBTs and − 6 V or less is required to completely cancel the gate noise voltage. From the IGBT design, the bias voltage of scaling IGBT requires −2 V to completely cancel the gate noise voltage.

  • ESR and capacitance monitoring of a dc-link capacitor used in a three-phase PWM inverter with a front-end diode rectifier

    Hasegawa K., Nishizawa S., Omura I.

    Microelectronics Reliability    88-90   433 - 437   2018年09月  [査読有り]

     概要を見る

    © 2018 Elsevier Ltd Condition monitoring plays an important role in estimating health condition of capacitors because the ageing of the capacitors is usually accompanied by an increase in equivalent series resistance (ESR) and a decrease in capacitance. Either capacitance or ESR cannot be a unique indicator of the lifetime of capacitors in some cases. This paper presents a condition monitoring method of a dc-link capacitor used in a three-phase PWM inverter with a front-end diode rectifier intended for motor drives. The monitoring method extracts both the ESR and capacitance of a capacitor under test from the actual ripple current and voltage without disconnecting the capacitor nor injecting an additional current. The monitoring method, therefore, can be implemented online. Experimental results verify that the monitoring method independently obtains the ESR and capacitance changes of the capacitor under test. This contributes to accurate lifetime estimation of dc-link capacitors.
