ABSTRACT:
A base drive circuit in a transistor inverter in which a control circuit controls the direction of current flow through an inverter main circuit transistor. Pulses from the control circuit are coupled through a photocoupler to amplifying transistors. A transistor, directly driven by the amplifying transistors, supplies reverse base current to the base of the inverter main inverter circuit transistor in the period immediately following the direct transition
