有源电力滤波器的控制电源设计

针对有源电力滤波器(Active Power Filter,简称APF)对控制电源的需求特点,设计了一种APF的控制电源。该电源初级输入采用交流电网和APF功率直流母线双电源供电方式,其中驱动电源和直流母线反馈电源均采用单端反激式DC/DC变换电路。该设计不但满足了APF在正常运行情况下的供电需求,还能够满足掉电保护、自启动等功能对控制电源的要求。实验和现场运行验证了该设计方案的有效性。

Power Supply Design for Controller of Active Power Filter

According to the specifications of the power supply used for the controller of active power filter(APF),a new APF power supply is designed.The design uses dual power supply including AC power grid and APF DC bus power.Both of the driving power and DC bus feedback power use single-ended flyback DC/DC converter.The power supply provides power for general operation of APF,and satisfies some special operating options,such as broken-down protection and self-starting of APF.The experiments and operations in field...
