<p>A plurality of controlled current inverter circuits each including a plurality of electrical current conducting legs having controlled rectifiers and associated commutating capacitors are connected in parallel and individually controlled to collectively supply an alternating current motor load with electrical power. At high speed, low required torque conditions, less than the total number of inverter circuits are maintained operative to thereby maintain sufficient current within the effective inverter circuit or circuits to sustain effective inverter commutation.</p> |
