Title: Self-excited inverter with suppressed current spikes

Abstract: A free-running inverter preventing excessive current spikes comprises a transformer and a switch means for alternately connecting, and then disconnecting, a DC voltage to a transformer primary winding which encloses a parallel combination of a saturating magnetic core and a non-saturating magnetic core. A transformer feedback winding enclosing only the saturating core drives the switch means during and between switch states. Switching between states is accomplished prior to saturation of the composite core.
