A multi-phase AC rectifier is a full-wave one with zero line. When it is used in 3-phase 4-line power supply system, it can output rectified voltage even if the phase is serisouly lost, so greatly increasing its reliability. A phase-loss, zero-loss monitor for three-phase power supply, which is made...
