Abstract
A hybrid contactor device that provides the ability to use the device with both AC and DC circuits is provided. The hybrid contactor includes a series-parallel arrangement of mechanical contacts with solid state devices, increasing the switching capacity of the mechanical contacts, and maintains galvanic isolation when open. The hybrid contactor includes two mechanical contacts, and is arranged so that one contact closes shortly before the other. The second contact forms a parallel circuit with an electronic switch.
