摘要
功率因数校正技术是抑制谐波电流、提高功率因数的行之有效的方法,近年来受到了越来越多的关注。本文选择Boost变换器为主电路拓扑,采用UC3854控制器,设计一容量为500W的单相有源功率因数校正电路,给出了主电路具体电路参数的计算。
Power factor correction technology is an effective method of restraining harmonic currents and increasing power factor, which has been attended more and more in recent years. Boost converter and UC3854 are used in designing a 500W APFC circuit.
