| 摘 要： | 针对传统开关电源因输入电路采用不可控二极管或相控晶闸管整流而存在输入电流谐波含量大、功率因数低的问题,提出了两种高功率因数开关电源的设计方案,分析了采用APFC技术和PWM整流技术来提高开关电源功率因数的原理,并采用Matlab7.6仿真软件对单相全桥电压型PWM整流电路和APFC电路进行了仿真。仿真结果表明,基于PWM整流技术的开关电源能更好地实现高功率因数,减少谐波电流。

| Abstract: | In allusion to problems of big harmonic content of input circuit and low power factor existing in traditional switching power supply which uses uncontrollable diode or phase-controlled thyristor for rectification,the paper proposed two design schemes of switching power supply with high power factor,analyzed principle of improving power factor by APFC technology and PWM rectifier technology,and used Matlab7.6 to simulate APFC circuit and voltage mode PWM rectifying circuit of single-phase full-bridge.The simulation result showed that the switching power supply based on PWM rectifier technology can improve power factor and reduce harmonic current. |
