An electric power supply system having a capacitor as an auxiliary power source in addition to a DC battery as a main power source. In this power supply system, the capacitor is charged only through a resistor by a source voltage of the DC battery to a voltage approximately equal to the source voltage. The resistor has a value of resistance considerably higher than that of a load to be connected with the power supply system. The DC battery is grounded at its positive or negative terminal. The power supply system is adapted for energizing an actuator of a safety device for a motor vehicle.
