摘要：
A phase-selective rectification technique applicable to multi-phase power supplies is proposed. By selectively turning on and off the low-cost thyristor rectifier bridge, the DC voltage of the rectified output of the multi-phase power supply is changed. Taking the six-phase shift 30 degrees power supply as an example, a six-phase rectifier bridge topology consisting of twelve thyristors is given. When the voltage of the six-phase shift 30 degrees power supply output is constant, three different DC voltage levels can be output by phase-selective rectification of the thyristors, and it is verified by simulation that the multi-voltage output of the DC side after multi-phase power rectification can be realized by using phase-selective rectification technology. In order to make the DC side voltage waveform with a certain ripple after rectification more stable, the influence of the selection of the DC side voltage-stabilizing capacitor on the output voltage ripple is further analyzed, and the required stabilizing capacitance value is verified by simulation.
