摘　　要：有源功率因数校正技术由于变换器工作在高频开关状态,而具有体积小、质量轻、效率较高、输入电压范围宽、THD小和功率因数高等优点,因此在现代电力电子技术中得到了广泛的应用。利用有源功率因数校正芯片UC3854设计了输出400 V的高功率因数直流电源,并用PSIM软件进行了仿真,功率因数接近于1。Active power factor correction technology due to the converter working in high frequency switch state,has features of small volume,light weight,high efficiency,wide input voltage range,THD small and high power factor. It has been widely used in the modern power electronic technology. In this paper,the active power factor correction UC3854 chip is used to design a 400 V DC power supply with high power factor. The DC power supply has carried on simulation with PSIM software and the power factor is close to 1.
