Abstract: A method for converting alternating current (AC) power to direct current (DC) power in a non-isolated power converter includes receiving a three-phase power supply, transforming the three phase power supply into six voltage phases, half-wave rectifying the AC current, applying a power factor correction to achieve DC power, and outputting a DC power signal. The three-phase power supply has an AC current. The six voltage phase is transformed at a secondary side of a three-phase distribution transformer, which includes a center tap located at the secondary side of the three-phase distribution transformer and one or more AC wire conductors. The AC wire conductors carry the transformed power supply. The half-wave rectification occurs at the secondary side of the three-phase distribution transformer. An arrangement of rectifier diodes on the AC wire conductors accomplishes the half-wave rectification. The output DC power signal has an output voltage at a DC output.
