A three-phase rectifier that suppresses waveform distortion of a three-phase input current is provided. A three-phase rectifier is a full-wave rectifier circuit that rectifies three-phase AC power from a three-phase AC power source into DC power, and inputs / outputs of each phase from ...
A three-phase full-wave diode rectifier is obtained by using two half-wave rectifier circuits. The advantage of this circuit is that it produces a lower ripple output than a half-wave 3-phase rectifier. This is because it has a frequency of six times the input AC waveform. A three-phase...
