提出了一种简单的无直流电压传感器单相PFC变换器，通过检测交流线电压波形。在传统的PFC变换器中使用的直流电压和交流电流传感器都不需要构建控制系统。传统的转换器电路与升压斩波电路在直流侧从整流电路被用作主PFC转换器电路。在控制系统中，诸如串联电感L和等效负载电阻值R/sub d/的电路参数用于产生正弦电流波形。直流电压由升压斩波器电路的指令输入信号k/sub d/（=E/sub d//E/sub a/）直接控制。由于对AC线电压E/sub a/的前馈控制并且不依赖于电路参数，所以DC电压调节小。可以获得与交流线电压同相的正弦电流波形。仿真和实验结果验证了该控制系统的可行性。
We propose a simple DC voltage sensorless single phase PFC converter by detecting an AC line voltage waveform. Both DC voltage and AC current sensors used in the conventional PFC converter are not required to construct the control system. The conventional converter circuit with a boost chopper circuit in the DC side from a rectifier circuit is used as the main PFC converter circuit. In the control system, the circuit parameters such as a series inductance L and equivalent load resistance value R/sub d/ are used to generate the sinusoidal current waveform. The DC voltage is directly controlled by the command input signal k/sub d/(=E/sub d//E/sub a/) for the boost chopper circuit. The DC voltage regulation is small because of the feed forward control for the AC line voltage E/sub a/ and no dependence of the circuit parameters. The sinusoidal current waveform in phase with the AC line voltage can be obtained. The feasibility of the proposed control system is verified by some simulation and experimental results.
