PULSE-WIDTH MODULATION CONTROL OF PARALLELED INVERTERS

摘要

A system includes a paralleled inverter circuit and a controller. The paralleled inverter circuit includes a first inverter and a second inverter. The controller is configured to control a first plurality of switches of the first inverter and a second plurality of switches of the second inverter based upon a control vector. The controller controls the paralleled inverter circuit using a first unit vector for a first time period and controls the paralleled inverter circuit using a second unit vector for a second time period. The first unit vector and the second unit vector are selected based upon the control vector, and the first time period and the second time period are determined based upon the control vector.
