| 摘 要： | 开关电源是实现电能转换和功率传递的重要设备。然而传统的开关电源功率因数低,谐波含量高,接入电网后,给电网带来了一系列严重的问题。文中设计了一款反激式PFC变换器的仿真模型,该模型是结合传统DC/DC变换中的反激式电路与基于Boost的PFC电路提出的,采用平均电流型控制作为本控制策略,最后运用Matlab仿真软件对模型进行了仿真,仿真结果表明该方案控制策略的正确性。

| Abstract: | The switching power supply is an important device for power conversion and power transmission.However,the low power factor and high harmonic content of the traditional switching power supply brings a series of serious problems to the power system.This paper designs a simulation model of the fly-back PFC converter combining the fly-back circuit in traditional DC/DC transform and the PFC circuit based on Boost with average current mode control as the control strategy.The circuit is simulated by Matlab software.The simulation results show that the scheme is a valid control strategy. |
