Abstract
A voltage regulator is disclosed for regulating the voltage supplied by an energy source such as a photovoltaic array. The regulator includes a thermally activated switch which is coupled in series between the regulator input and output. A control circuit monitors the voltage supplied to a load and generates a control signal which is responsive to the measured to the load voltage. A heater, responsive to the control voltage, is positioned near the thermally activated switch and causes the switch to open when the sensed voltage rises above a prescribed limit. Hysteresis in the voltage regulator is provided by thermal insulation which retards the dissipation of heat from the vicinity of the switch causing the switch to remain open.
