ABSTRACT OF THE DISCLOSURE A three-phase full wave bridge type rectifier utilizing silicon controlled rectifiers connected to receive a three-phase input electrical signal, a switch- ing network utilizing four silicon controlled rectifiers connected to receive and gate full wave rectified three- phase signals from the three-phase rectifier to provide desired positive and negative output signals, a trans- former having a single primary winding or multiple separate windings connected in parallel or series to receive the output of the switching network, and timing structure for timing the rectifier and switching network to produce alternate positive and negative full wave rectified three-phase signals at a selected frequency from the three-phase electrical energy input and gate them to the transformer primary, and the method of full wave frequency conversion comprising full wave rectifying three-phase electrical energy and gating the three-phase rectified electrical energy in alternate positive and negative electrical cycles to a transformer primary winding, or windings.
