Abstract
The dual inverter system includes a first inverter connected to one end of a stator coil of the motor and a second inverter connected to the other end. The controller is capable of executing a single mode in which the second inverter is disconnected from the battery and the motor is driven only by the first inverter. When driving the motor in a single mode, the controller selects one of an upper short-circuiting circuit that turns on all the upper SW devices of the second inverter and turns off all the lower SW devices, and a lower short-circuiting circuit that turns on all the lower SW devices of the second inverter and turns off all the upper SW devices. The controllers compare the loads of the upper SW devices and the lower SW devices of the second inverters.
