Abstract

This study investigates the instability phenomena of an active power factor corrector (PFC) circuit based on a buck-boost converter. First, the circuit is analyzed, and the state space mathematical model of the converter is derived. Second, Matlab/Simulink and IsSpice are used to construct and simulate the voltage-mode control model of the buck-boost power factor corrector. The intermediate-scale instability phenomena of inductance current waveforms, control voltage, output voltage waveforms and phase-plane portraits are observed by varying the load resistance. These waveforms exhibit intermediate-scale instability phenomena in specific circuit parameters. Furthermore, the two software simulation results are compared, confirming the validity of this mathematical model.
