摘要
电磁兼容标准是强制性的,因此满足特定的电磁兼容标准是功率因数校正技术研究的重要内容。无源功率因数校正技术具有简单及成本低的优点,在小功率应用场合具有广阔的前景。主要是针对开关电源功率因数校正的效果进行分析,并对单相无源功率因数校正(PFC)进行仿真,从仿真中得出接入电感的大小会影响功率因数校正效果。
The modification of the new version of EMC specifications should be taken into account for design in order to comply with the standards.Passive solutions are very attractive topologies for low power applications,due to the theirs simplicity and low cost.This paper mainly analyses by the result to the power factor corrected of the switch power,and there is a simulation of the singl-phase passive PFC circuit with SIMCAD,and it gets a conclusion from the simulation that is the size of inductor has a important influence towards power factor.
