ABSTRACT:
An off-line switcher flyback-type power converter circuit is designed having energy and operative control circuits operating off a tertiary winding of the power transformer. A delayed current shutdown circuit permits starting in the face of high demand current loads whereby the load is supplied with bursts of current as start up is cyclic and delayed shutdown is also cyclic in this situation.
