Abstract
An inverter system is provided such that the system includes a direct-current (DC) voltage supply, an inverter electrically coupled with the DC voltage supply, an electric machine electrically coupled with the inverter, and a controller coupled with the inverter. The inverter has a plurality of legs, each leg including two switches operating complementary to each other, an auxiliary leg having a pair of auxiliary switches, and a resistor coupled parallel to one of the auxiliary switches. A controller is coupled with the inverter and is operative to activate or deactivate the auxiliary leg of the inverter. The controller activates the auxiliary leg to discharge the capacitor or the DC bus through the resistor.
