Abstract
A driving apparatus includes an inverter and a controller. The inverter converts, based on pulse width modulation (PWM) signals, an input voltage into output voltage signals that are used to drive a multi-phase load. The controller includes: a sequence generating module generating a first switching sequence and at least one second switching sequence based on duty cycle values; a selecting module selecting, to serve as a selected switching sequence, one of the first and second switching sequences that is determined to make phase currents which flow through the multi-phase load due to the output voltage signals have lowest total harmonic distortion; and an output generating module generates the PWM signals based on the selected switching sequence.
