Abstract
An electrified vehicle includes: an energy storage device; a traction motor including a three-phase open-end winding; a first inverter including a first upper arm and a first lower arm and connected to a first end of the three-phase open-end winding; a second inverter including a second upper arm and a second lower arm and connected to a second end of the three-phase open-end winding; a switch provided between the first and second inverters; and a controller configured to control the first and second inverters and the switch. When the controller confirms that the absolute value of a zero-sequence current is equal to or larger than a threshold while the switch is on and the first and second inverters are being driven to perform switching, the controller determines that the switch has failed open.
