Abstract:

针对传统有源钳位正激(ACF)变换器存在输出二极管反向恢复损耗,以及轻载时不能实现软开关的问题,提出了ACF二次侧谐振(SSR)PWM(ACF-SSR-PWM)Buck-Boost型变换器,分析了ACF-SSR-PWMBuck-Boost型变换器的工作模式及其稳态特性。分析结果表明ACF-SSR-PWMBuck-Boost型变换器可以在全负载范围内实现主开关管、辅助开关管的零电压开通(ZVS)和输出二极管的零电流关断(ZCS),其电压传输比与负载、开关频率和占空比无关,呈现出DC-DC变压器(DCX)的工作特性。与二次侧谐振ACF变换器相比,ACF-SSR-PWMBuck-Boost型变换器减小了辅助开关管的电流应力和主开关管的关断电流。最后,搭建了一台200V输入、50V/1.6A输出的实验装置,验证了理论分析的正确性。
