Abstract
A drive circuit for an electric machine is disclosed. In one example, the drive circuit utilizes a bootstrap capacitor and a bootstrap diode, followed by a regulator, as a basis for driving a gate of a power stage of an inverter. The regulated voltages from the bootstrap capacitor and bootstrap diode eliminate the need for using a transformer for driving the gate of the power stage of the inverter.
