Abstract :
According to the essential operational principle of High Power Factor PWM rectifier, a simulation model of AC constant power load is proposed. The input current of this model is ensured to follow the input voltage and the consistence in their waveforms is achieved. This model can calculate the RMS of input current and then generate an appropriate current waveform corresponding to the harmonics contained in input voltage. Therefore the input power of the model is constant even with the influence of the harmonics. Compared with the experimental result of a high power factor rectifier behaving as a CPL, the simulation results in Matlab software verify the correctness of this model.
