This article presents the GaN-based non-inverting buck-boost (NIBB) dc–dc converter for high-frequency and high-efficiency operation. The feedback control was designed and implemented using FPGA for the operation of the converter at a switching frequency of 500 and 800 kHz under different operating load conditions.

This paper proposes an adaptive frequency control strategy for the unidirectional DC/DC converter based on Dual-bridge LLC (DBLLC) resonant converter to eliminate the circulating interval (CI), which causes high conduction loss. The LLC resonant converters are the preferred choice to select of DC/DC converter topology for on-board charger (OBC) due to it provides many advantages such as high efficiency, high power density.

The scientific and technological evolution of state-of- the-art devices since its inception has made a leap in power rating. This ultimately leads to extend the horizon for operating range of a single device considering blocking voltage and current capability. However, higher current/voltage ratings of power devices are required for high power conversion and control Enhancement and optimization of the performance of power semiconductor devices are of fundamental concern, especially for the system consisting of parallel/series connected devices
