摘要
A three-phase rectifier converts three-phase alternating current (AC) power supplied from a three-phase AC power supply into direct current (DC) power. The three-phase rectifier includes a full-wave rectifier circuit, a bidirectional switch circuit, and a controller. The full-wave rectifier circuit rectifies three-phase AC power to DC power. The bidirectional switch circuit switches on and off inputs of respective phases from the three-phase AC power supply to the full-wave rectifier circuit. The controller detects voltages of the respective phases of the three-phase AC power supply, generates switching patterns for the respective phases to switch the bidirectional switch circuit on and off based on the detected voltages of the phases, and controls switching of the bidirectional switch circuit based on the switching patterns.
