采用移相控制有源整流的全桥变换器
|
摘要
当移相控制有源整流全桥(PSCAR-FB)变换器中的输出整流二极管反向恢复时,整流二极管存在很高的尖峰电压,增加了二次侧开关管和二极管的电压应力。为解决上述问题,在一次侧引入了1个谐振电感和2个箝位二极管的辅助网络。详细分析了该变换器改进后的工作原理及稳态特性,并给出了主要参数的具体设计方法。在此基础上,设计了一台1.25 kW实验样机并进行了实验验证,实验结果证实了所提方法的可行性。
The output rectifier diodes suffer a high voltage spike resulted by the reverse recovery of the rectifier dio-des in the PSCAR-FB(Phase-Shifted Control Active Rectification Full Bridge) converter,which increases the voltage stress of the secondary switches and diodes. In order to solve the above problem,an auxiliary network with one resonant inductor and two clamping diodes is introduced in the primary side. The working principle and steady-state characteristics of the improved converter are analyzed in detail,and the specific design method of main parameters is given. On this basis,a 1.25 kW experimental prototype is built and tested. The experimental results verify the feasibility of the proposed method.
