Abstract
The present invention discloses a discontinuous pulse width modulation method, including: shifting an obtained first three-phase modulation wave upwards and downwards to obtain an upward-shifted three-phase modulation wave, a down-shifted three-phase modulation wave, an upward-shifted zero-sequence component and a down-shifted zero-sequence component; calculating a start time-point of a transition interval, a target zero-sequence component within a transition interval and an end time-point of a transition interval based on the above modulation wave and its zero-sequence component; adding the first three-phase modulation wave and the target zero-sequence component together to obtain a target three-phase modulation wave. The discontinuous pulse width modulation method of the present invention can slow down a modulation wave change within the transition interval, effectively abate the voltage and current oscillation of the common-mode suppressor unit and decrease the stress of the common-mode suppressor unit device.
