ABSTRACT:
A power supply system for feeding low cold resistance incandescent lamps from a diode-rectified alternating current generator where the system does not have a battery or other voltage source for energizing the lamps. A control circuit is connected between the generator and lamps that includes a resistor that can be bypassed by the closure of relay contacts. The control circuit energizes the lamps such that generator voltage does not collapse when the relay contacts close. The resistor can have a negative temperature coefficient of resistance.
