Abstract
An inverter circuit having a pair of transistors connected to alternately and repetitively apply electrical energy to an inductive load. Short duration turn-off pulses are alternately applied to the transistors, and means are connected so that when each transistor is turned off, fly-back current induced in the load is applied to the other transistor to create a stored charge for turning it on and keeping it on until it receives its next turn-off pulse. Thus, no externally supplied repetitive forward base current is required.
