Traditional three-phase PFC converters based on one-cycle control (OCC) exhibit instabi- lity at light load conditions.This will cause much more harmonic current which is harmful to the syterm.To overcome this disadvantage, this paper introduces a modified three-phase power factor correction(PFC) converter based on one-cycle control in aircraft electric power system. The input voltage multiplies a gain and its result is added to the actual sensed current,then the sum of them is compared with the sawtooth waveform to yield switching signal.This is the modified contorl mathod. Finally the MATLAB simulations at heavy and light loads as well as the transfer between them are carried. The simulation results show that the improved control circuit can achieve unity power factor and exhibit stability at light loads.
