1. A dual snubber circuit for a switching circuit in an inverter circuit for inverting DC power provided on a first supply potential and a second supply potential into AC power on an output line, said switching circuit being coupled between at least one of said supply potentials and said output line, said dual snubber circuit comprising:

  • first snubber means coupled across said switching circuit for performing a first snubbering function in a switching operation of said switching circuit; and

    second snubber means coupled between said output line and a low impedance potential other than said first and second supply potentials, for performing a second snubbering function in the switching operation of said switching circuit, said second snubbering function comprising suppressing and controlling oscillations resulting from said switching operation.
