Abstract:
1. A method of delivering power to a load comprising: providing a switching circuit comprising a first switching pole circuit disposed across positive and negative voltages coupled to a voltage supply, and a second switching pole circuit disposed across positive and negative voltages coupled to the voltage supply; switching at least one switch of the first switching pole circuit so as to deliver a current from a load to the first switching pole circuit; and switching at least one switch of the second switching pole circuit so as to further deliver current from the load to the second switching pole circuit, the switching of the at least one switch of the second switching pole circuit taking place after a first switching of the at least one switch of the first switching pole circuit, but before a second switching of the at least one switch of the first switching pole circuit, so as to substantially reduce a diode reverse recovery current in the first switching pole circuit.
