Title:
POWER CONVERSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/008381
Kind Code:
A1
Abstract:
A power conversion system as one embodiment of the present invention comprises: a power converter that converts inputted power and outputs power for each of a plurality of phases, using a plurality of legs each of which has an upper arm and a lower arm; and a control apparatus (30) that controls pulse currents flowing through each of the legs, by controlling the upper and lower arms of each of the legs. The control apparatus (30) calculates duty-ratio commands for each of the legs for one control cycle, for each of the phases, and changes the phases of the calculated duty-ratio commands for a first leg and a second leg, among a plurality of legs provided by a phase, such that a period of time wherein a plus pulse current flows through the first leg will overlap with a period of time wherein a minus pulse current flows through the second leg, during one control cycle.
