Abstract
A multiple step-up rectifier circuit has a transformer, diodes connected in series with each other, and first, second, third and fourth capacitors. An AC signal source is connected to a primary winding of the transformer. A neutral point of a secondary winding of the transformer is grounded. One terminal of a series circuit of the diodes is connected to the neutral point such that the diodes are biased in the same direction. The first capacitor is connected across the two terminals of a series circuit of the diodes. The second capacitor is connected to a first output terminal of the secondary winding of the transformer and the common connecting point of a first pair of diodes. The third capacitor is connected between a second output terminal of the second winding of the transformer and the common connecting point of a second pair of diodes. The fourth capacitor is connected between a third output terminal of the secondary winding of the transformer and the common connecting point of a third pair of diodes.
