An automatic feedback and control system for operating a load off of a multi-phase rectified rotary field system of a motor vehicle and for increasing the voltage and current to the load upon demand. The multi-phase rectified rotary field system comprises a rotatable coil for forming the rotary field when excited and stationary windings having an output coupled thereto by way of rectifier means. A DC power supply is coupled to said output. A regulator is provided having an input coupled to the DC power supply and and output coupled to the rotatable coil. Non-polarized capacitors are provided and a switch is coupled to the capacitors and to the DC power supply. The switch when closed, electrically connects the capacitors between the stationary windings and the rotatable coil and electrically connects the DC power supply to the rotatable coil. The switch when opened, interrupts the electrical connection of the capacitors between the stationary windings and the rotatable coil and interrupts the electrical connection of the DC power supply with the rotatable coil. Control means is coupled to said output of the regulator for causing the switch to be closed when the output of the DC power supply drops to a given level.
