本文提出了另一种候选人的直流/直流转换器在电动汽车车载充电器。保持类似于传统谐振转换器的拓扑特性，它是以恒定频率PWM进行充电控制。由于转换器使用次级谐振回路，因此软开关和谐振操作可以分离。提出了一种切实可行的设计方法，保证了PWM SRT变换器的正常工作，并以一台6.6 kW的样机验证了该方法的可行性。
This paper suggests another candidate for a dc/dc converter in an electric vehicle onboard charger. Maintaining topological characteristics similar to those of conventional resonant converters, it is operated with a constant frequency PWM for charging control. Since the converter uses a secondary resonant tank, soft-switching and resonant operations can be separated. A practical design procedure is suggested to guarantee the normal operation, and the feasibility of the PWM SRT converter is verified with a 6.6-kW prototype charger designed by the procedure.
