摘要
为提高逆变器或不间断电源控制系统的功率因数,抑制输入电流的谐波,将单周期控制技术应用到一种新型的单电感三电平无桥升压功率因数校正电路,分析其充放电的工作原理与单周期控制模式,建立了单周期控制的单电感三电平无桥升压电路的Simulink模型。结果表明:单周期控制能够抑制输入电流中的谐波,总谐波畸变率为0.1,输入功率因数达0.995。
Aimed at improving the power factor of inverter or uninterrupted power supply control system and inhibiting input current harmonic,this paper introduces the application of one-cycle control strategy to a novel single inductor three-level bridgeless boost power factor correction,the analysis of the principle of charging and discharging and one-cycle control strategy,and the development of the simulation mode of single inductor three-level bridgeless boost power factor correction controlled by one-cycle.The results show that one-cycle control can inhibit the input current harmonic,giving a total harmonic distortion rate of 0.1,and the input power factor of 0.995.
