Title:
POWER CONVERSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/118767
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce surge associated with changing of switching states without increasing the torque ripple of a motor. A first switching signal (Sbp) for controlling the switching of a boost converter is generated based on the comparison between a first duty command value (Db*) of the boost converter and a first triangular wave carrier (carrier1). A second switching signal (Sup1) for controlling the switching of an inverter is generated based on the comparison between a second duty command value (Du1*) of the inverter and a second triangular wave carrier (carrier2). The second triangular wave carrier (carrier2) is generated so that the frequency thereof becomes equal to that of the first triangular wave carrier and the phase thereof becomes different from that of the first triangular wave carrier by 180 degrees.
