Abstract
A low powered system for providing sufficient current to a fuel control mechanism drive. The system may have a fuel control mechanism pick circuit that has an energy storage mechanism for providing a large amount of current for a short time to the fuel control mechanism drive. A safety switch may be enabled with a special signal to let current flow to the fuel control mechanism drive to operate a corresponding fuel control mechanism for controlling fuel to a pilot light or heating element. The pilot light or heating element may provide heat to a thermoelectric source that generates electrical power from the heat. The electrical power may go to a single DC-to-DC converter and voltage clamp for providing a voltage source to a microcontroller and other circuits of the system. The pick circuit may prevent a harmful reverse flow of current from the storage mechanism to the thermoelectric source.
