Abstract
A voltage doubler rectifier circuit which can be switched to different mains voltages. The circuit includes two pairs of series-coupled diodes and respectfully arranged to form a full-wave rectifier. A first terminal of a coil is connected to the positive side of the full-wave rectifier, and a second terminal of the coil is connected to an anode of a fifth diode. The anode of a sixth diode is connected to a cathode of the fifth diode via two series-coupled capacitors, and a cathode of the sixth diode is connected to a further coil. A first terminal of a switching means is connected between the anode of the fifth diode and the second of the coil. A second terminal of the switching means is connected to a coil which is connected to the negative side of the full-wave rectifier. A switch is connected between the connecting line of the diodes in one of the diode-pairs in the full-wave rectifier and the line connecting the capacitors.
