Abstract
An inverter contact switch has a first pair of spaced fixed contacts connected to respective terminals of an inverter circuit for selectively disconnecting and connecting the inverter to a DC power bus. A first pair of spaced movable contacts are positioned on opposite sides of the fixed contacts. A drive actuator is coupled to the movable contacts for concurrently driving the movable contacts into substantially simultaneous engagement with the pair of fixed contacts for establishing a circuit path from one of the fixed contacts through each of the movable contacts to another of the fixed contacts. The switch may include a second pair of fixed and movable contacts operatively connected to a DC return bus and another terminal of the inverter for isolating the inverter from both the power and return buses. The switch also includes flux concentrators positioned adjacent the fixed contacts for concentrating electromagnetic flux generated by current through the closed contacts so as to counteract repulsive forces at the contact interfaces due to very large inverter currents.
