Abstract

A low-cost linear gate pulse generator and power supply designed for use in gating controlled rectifiers and, in particular, controlled rectifiers in a three-phase bridge arrangement. The power supply portion supplies power to both the gating circuits and auxiliary control circuits and necessitates the use of only three low-cost single-phase transformers unlike other circuits which historically use separate transformers for control power, timing waves and pulsing.
