Current balancing structure for semiconductor switching devices

A current balancing structure in which an alternating current output is produced by alternately connecting a DC potential to an output voltage bus through the switching action of a paralleled array of semiconductor devices forces equal current to flow through each device. During switching intervals, some semiconductor devices may "turn-on" or "turn-off" faster than others thus possibly forcing any conductive devices to carry a much higher current than when all the devices are conducting. Diodes protect the conductive devices by providing alternative circuit path to a DC reference potential voltage bus when one device becomes non-conductive before another paralleled device.
