摘　　要：根据功率因数校正的基本原理和物理意义,理论上推导了一种新型直接控制算法,并通过仿真分析和试验研究进行了验证。结果表明,该方法通用性很强,无需输入电压检测,具有更宽的调功范围,且适合任何输入电压波形,因而在传统交流电压供电或分布式电源应用中,如车载交流正弦波电源、交流方波电源的功率因数校正中具有重要应用价值。为了描述问题方便,提出了调功范围、正弦交流PFC、方波交流PFC和直流PFC等概念。According to the basic principle and physical significance of power factor correction,a new direct control algorithm was derived in theory and verified by simulation analysis and experimental research.The results showed that this method was strong universal,had a wider power-adjusting range without input-voltage detection and was suitable for any input voltage waveform.Therefore power factor correction had important value in the application of traditional ac voltage supply and distributed power supply,such as vehicular AC sinusoidal power source and AC square wave power source.To describe the problem conveniently,the conceptions of power-adjusting range,AC si-nusoidal PFC,AC square wave PFC and DC PFC were proposed.
