An inverter circuit has first and second input terminals adapted to be connected to the voltage. First and second switching devices are connected in series at a first junction. The first switching device connected to the first input terminal, and the second switching device adapted to be connected to one side of the load. Third and fourth switching devices connected in series at a second junction. The third switching device is connected to an opposite side of the load, and the fourth switching device connected to the second input terminal. A voltage divider is connected between the first and second input terminals and provides an output potential. A first current steering device is connected between the potential from the voltage divider and the first junction. A second current steering device is connected between the potential from the voltage divider and the second junction. By switching on the second and third switching devices and then the first and fourth switching devices, and then, switching off the first and fourth switching devices before switching off the second and third switching devices, the inverter circuit prevents more than half of the voltage from being connected across any one of the switching devices.
