ABSTRACT:
A half-bridge inverter having first and second power FETs is provided with a high-speed, highly efficient drive circuit for driving the FETs from a single control signal. A single 15 V supply provides energy for charging the gate electrode of the first FET, as well as for a floating source for charging the gate electrode of the second FET. A single bipolar transistor receives the control signal for controlling operation of the first FET, while a current source, a bipolar transistor in series with a resistor, receives the control signal to effect operation of a third bipolar transistor, thereby to control operation of the second FET.
