Title:
ELECTRIC VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/193964
Kind Code:
A1
Abstract:
An electric vehicle control device (100) comprises: main transformers (102) that convert AC voltage input to an input winding from an AC power source, and that output the converted AC voltage from each of a plurality of output windings; a plurality of converter main circuit units (103) each of which is respectively connected to a plurality of secondary windings that are included in the plurality of output windings, and which convert the AC voltage output from the connected secondary windings to DC voltage; and a plurality of converter control units (111) for which the control target thereof is each of the plurality of converter control units (103), each of which compares a signal wave and a carrier wave, and which thereby execute pulse-width modulation control on the converter main circuit units (103) that are the control targets. In accordance with operating status of loads which receive power supply via pre-determined output windings from among the plurality of output windings, each of the converter control units (111) determines the phase-angle correction amount for at least one of the signal wave and the carrier wave.
