ABSTRACT:
A full wave rectification circuit for use with a three-phase input signal connected in a wye configuration for rectifying a line to neutral high input voltage is disclosed. The rectification circuit has two portions. A first portion generates a control signal which oscillates every 60.degree. and is switched in phase with one of the input signals. A second control signal, also oscillating in 60.degree., but completely out of phase with respect to the first oscillating signal is also generated. The two oscillating signals are used in a SCR switch configuration to switch the rectification circuit every 60.degree. thereby rectifying the peak voltage portion of each phase.
