ABSTRACT:
An improved electrical power converter is disclosed. The electrical power converter utilizes a pulse width modulator responsive to the voltage across a tertiary winding of the power transformer. The electrical power converter includes a feedback control circuit for providing a regulating voltage to the pulse width modulator that is substantially proportional to the voltage across the tertiary winding with the voltage spikes caused by any leakage inductance in said power transformer removed. The feedback control circuit includes a spike compensator circuit that utilizes leakage inductance produced voltage spikes to compensate for output voltage degradation due to heavy loads.
