Abstract
Circuits, systems, and methods are disclosed to eliminate the requirement for an external electromechanical contactor. Integrating contactor circuits with a motor controller reduces cost. Additionally, the cost of the contactor circuit may be reduced by providing transistors designed to block current in only one direction in the event of an electrical fault corresponding to an electrical drive direction.
