Abstract
Two enhancement mode MOSFETs in series are used to provide a solid-state switch. The MOSFETs are turned on by a photovoltaic array. Resistors in series with the MOSFETs serve to provide a control voltage to current-limit the circuit. An additional photovoltaic array is used to supply drain to gate bias when the switch is off to minimize device capacitance. The circuits can be cascaded to raise the voltage-handling limits.
