Abstract :
MANY different converter circuits have been developed. They may be classified as single-way or double-way, depending upon the polarity of the current pulses which flow in the d-c windings of the rectifier transformer. Single-way circuits are most common in power rectifiers and require a transformer with an even number of d-c windings per a-c winding in order to avoid saturation of the transformer core because of the direct current flowing in each one of the windings.
