Patent ID: 8536823

Claim:
A driving method for driving a polyphase inverter to be implemented by a driving device, said driving method comprising: A) configuring the driving device to receive a reference input that includes a fundamental frequency component, and a previously generated feedback signal, wherein the feedback signal is derived from a control signal that is an output of a quantizing module; B) configuring the driving device to generate an error signal that corresponds to a difference between the reference input and the previously generated feedback signal; C) configuring the driving device to attenuate the frequency components of the error signal outside a predetermined frequency band to the minimum; D) configuring the driving device to generate an optimum signal so that the magnitude of error signal within a predetermined frequency band is minimum; and E) configuring the driving device to quantize the optimum signal, and to generate driving signals that correspond to the quantized optimum signal, wherein the driving signals are for driving the polyphase inverter.
