Abstract
A power converter includes an unfolder with an input connection with three terminals that connect to a three-phase AC power source and that has an output connection with a positive terminal, a negative terminal and a neutral terminal. The unfolder unfolds the bipolar AC voltages into two unipolar piece-wise sinusoidal DC voltages offset from each other by a half of a period. The power converter includes a three-input converter that produces a DC voltage output across output terminals. The three-input converter includes a positive input connection connected to the positive terminal, a negative input connection connected to the negative terminal and a neutral input connection connected to the neutral terminal. The three-input converter includes switches that selectively connect a voltage to the positive, negative and neutral input connections across a primary transformer winding of a transformer. A secondary transformer winding is connected to the output terminals through a rectification section.
