Abstract
An inverter phase leg for a DC-AC inverter includes a high supply line and a low supply line across which a DC voltage is provided. A high side gate controlled switch is connected to the high supply line and a low side gate controlled switch is connected to the low supply line, with an output node between the high side switch and the low side switch. An inverting driver is connected to the high side gate controlled switch. The inverting driver's voltage source is configured in such a way as to hold the high side gate controlled switch off during the turn on cycle until the driver output has overcome the negative bias generated across the high side switch gate, producing high immunity to spurious turn on. A digital isolator is connected between the inverting driver and a control signal for switching the inverter phase leg. A differential transmitter and differential receiver may be used to further increase noise immunity.
