Abstract
A zero-voltage switching ARCP-based converter that is capable of balancing its DC-link capacitor voltages and a method of balancing the voltages of the DC-link capacitors of an ARCP-based converter are disclosed herein. Each phase of the converter comprises a main section, an auxiliary section, and a control section. Main switches of the main section synthesize one or more reference voltage at the output of the phase. The auxiliary section facilitates zero voltage switching of the main switches. The control section provides gate signals for the main switches and the auxiliary switches based on the feedback signals from the converter to control the main and the auxiliary circuits. The method balances the voltages of the DC-link capacitor by utilizing ARCP-based hardware. The disclosed method minimizes switching losses and other EMI problems experienced by other converters.
