Claim:
1. An inverter phase leg in a DC to AC converter comprising a high supply line and a low supply line across which a DC voltage may be provided, a high side gate controlled switch connected to the high supply line and a low side gate controlled switch connected to the low supply line, the switches connected between the high supply line and the low supply line with an output node between the high side switch and the low side switch, comprising: an inverting driver connected to the high side gate controlled switch and having an input voltage from a control signal, an output voltage for switching the high side gate controlled switch, and a driving voltage; and a source of a constant biasing first DC voltage between the output node and the inverting driver; wherein the driving voltage is set to cause the output voltage of the inverting driver to be zero until the input voltage exceeds the first DC voltage.
