- Traditional rectifier circuit by the diode or thyristor, work to produce a large number of harmonics. Active power factor correction (PFC) on this basis to add high-performance full-control power electronic devices, such as MOSFET and IGBT, and control the input current to make it close to the sine wave and the unit power factor. In recent years, with the requirements of the performance of electrical equipment continues to improve, this technology has become a hot spot in the field of power electronics research, and has been widely practical application. For the single-switch and DC-side Boost-type boost circuit, this paper uses the current hysteresis control strategy and PI regulator on the DC side of the fixed voltage control. Analyze the continue current mode (CCM) and the discontinue current mode (DCM). Then the harmonic analysis and switching loss analysis are carried out for the two models. Through the PSCAD simulation, total harmonic distortion (THD) of the current harmonics is low by the discrete Fourier transform (FFT) of the AC current waveforms of the two models. In this paper, we use parallel switch on the buffer circuit to simulate the switching losses, DCM control can be a good way to reduce the opening loss of the switch.
