Abstract
A solid state switch includes a solid state device having an input terminal, an output terminal and a gate terminal; a quick response circuit selectively operable to initially place the solid state device in a conducting state; and a sustained response circuit selectively operable to maintain the solid state device in the conductive state after the quick response circuit. The input terminal and the output terminal are connected when the solid state device is in the conducting state and the input and the output terminal are disconnected when the solid state device is not in the conducting state.
