ABSTRACT:
An apparatus and method for accomplishing DC-to-AC power conversion that combine the AC outputs of n interleaved, time division multiplexed inverters and steer the secondary pulses positively or negatively, as commanded by the time varying reference signal, such that the effective switching, or sampled-data, frequency of any of the inverter or pulse-steering transistors. The n interleaved inverter system can, in turn, be paralleled such that, relative to a single inverter supplying all the power, the losses for any inverter transistor are 1
p, n due to time multiplexing and p due to paralleling.
