Patent ID: 7385372

Claim:
A system comprising: an auxiliary power system adapted for an off-road traction vehicle, comprising: an active rectifier comprising an Insulated Gate Bipolar Transistor, said active rectifier a self-commutated infeed/regenerative feedback unit, said active rectifier adapted to receive a first AC signal from an alternator and provide a first DC signal to a DC bus; and an active Insulated Gate Bipolar Transistor inverter adapted to receive the first DC signal from the DC bus and provide a second AC signal to an auxiliary device; wherein the second AC signal is a space vector modulated AC signal, said space vector modulated AC signal based upon a sampling interval that is smaller than approximately one sixth of a cycle of a target output fundamental, Insulated Gate Bipolar Transistors of said active Insulated Gate Bipolar Transistor inverter adapted to be switched via an application of each of two active vectors for a predetermined sub-interval of said sampling interval.
