Abstract
A three-phase alternating current (AC) to direct current (DC) converter may include a three-phase AC filter receiving a three-phase AC power supply, a plurality of three-phase current source rectifiers (CSR) connected in parallel with each other and connected to a three-phase AC filter, and an output filter connected to the CSR's to generate a DC output. Each of the CSRs may include six switches and a free-wheeling diode. Each of the three filtered AC inputs from the three-phase AC filter may be connected via a switch of the six switches to selectably send current into a positive line, and each of three filtered AC inputs from the three-phase AC filter may be connected via another switch of the six switches to selectably receive current from a negative line. The free-wheeling diode may have a cathode connected to the positive line and an anode connected to the negative line.
