An inverter phase leg (100) for an AC-DC inverter (10, 20) includes a high supply line (12, 22) and a low supply line (14, 24) across which a DC voltage is provided. A high side gate controlled switch (110) is connected to the high supply line and a low side gate controlled switch (114) is connected to the low supply line, with an output node (104) between the high side switch and the low side switch. An inverting driver (116) is connected to the high side gate controlled switch (114) and a source of first DC voltage is provided between the output node (104) and the inverting driver (116). A digital isolator (120) is connected between the inverting driver (116) and a control signal (128) for switching the inverter phase leg (100). The driving voltage of the inverting driver (116) is set to cause the output voltage to be zero until the input voltage exceeds the first DC voltage. |
