A charge-transfer voltage converter transforms a high voltage to a lower value without the use of a conventional transformer. Two capacitors are connected together to form an electrical circuit. The circuit is then broken in one place and a switch is inserted to form a continuous circuit. One of the two capacitors is charged to a high voltage. The switch is turned on and off rapidly and this transfers a charge from the charged capacitor to one which was initially uncharged. By controlling the duty cycle and/or repetition rate of the switch between the two capacitors, the output voltage of the capacitor which was initially uncharged can be maintained between the limits of zero volts and the value to which the supplying capacitor was initially charged. Thus, voltage transformation has been achieved without the use of a conventional transformer.
