ELECTRIC VEHICLE CONTROL DEVICE
DRIVE
April 26, 2017
An electric vehicle control device (100) includes: a main transformer (102) to convert AC voltage input to an input winding thereof from an AC power source, and output converted AC voltage from each of a plurality of output windings; a plurality of converter main circuits (103), each connected to one of a plurality of secondary windings included in the output windings, to convert AC voltage output from connected secondary windings into DC voltage; and a plurality of converter controllers (111), each targeting for control one of the converter main circuits (103), to control by pulse width modulation the control-target converter main circuit (103), by comparing a signal wave and carrier wave. Each of the converter controllers (111) determines a phase angle correction amount of the signal wave and/or the carrier wave, in response to operating state of a load supplied power through a predetermined output winding among the output windings.
