Abstract
Abstract A circuit for supplying pulse energy to a load such as a laser. The circuit is energized from a three phase supply. One channel operates on the crests of the phase voltages supplied while a second channel operates on the crests of the phase to phase voltages. The circuit provides, in effect, multiple phase rectification in a line type pulser operation without a rectifying transformer.
