Abstract
A multiple step-up rectifier circuit comprises a transformer, a series circuit of diodes, a first series circuit of capacitors, a second series circuit of capacitors and a third series circuit of capacitors. An AC signal source is connected to the primary winding of the transformer. The secondary winding of the transformer has a tap connected to the ground. The tap is also connected to one end of the series circuit of diodes, so that the diodes are biased in the same direction. The first series circuit of capacitors is connected between both ends of the series circuit of diodes. The second series circuit of capacitors is connected between one end of the secondary winding and a connecting point between the diodes. The third series circuit of capacitors is connected between the other end of the secondary winding and another connecting point between the diodes. A connecting point between the capacitors is also connected to a connecting point between the diodes. Another connecting point between capacitors is connected to another connecting point between the diodes. A third connecting point between the capacitors is connected to yet another connecting point between the diodes.
