A new scheme of a diode-capacitor network, used as a DC voltage multiplier is proposed. The circuit operates in combination with a high-frequency switch. In contrast to the present similar circuits, during the operational process the capacitors are not shortened by the switch and therefore the large discharge current stresses donpsilat influence the circuit. The circuit provides the multiplication of the input voltage having a smooth (very small ripples) input current and output voltage. The advantages of the proposed circuit make it very appropriate for use with alternative sources of energy. SPICE-simulation and the experimental results confirm the theoretical expectations.
