Abstract
A circuit for controlling a power converter featuring BJTs, through use of a control winding on the transformer that provides the base drive for the BJTs is disclosed. This controller can control the control winding current, thus modifying the commutating of the current or stopping the oscillations. It can provide unidirectional shorts to prevent commutation and can also provide an initial power pulse to control the start or operation of the power converter.
