Abstract :
The charge control method is a suitable control scheme for achieving high switching frequency for the three-phase buck rectifier. Key improvements are made to the original control scheme allowing for input power factor compensation and the improvement of the input current waveform quality in the presence of an EMI filter. The modified control scheme is demonstrated using a 2 kW SiC JFET-based buck rectifier with 150 kHz switching frequency.
