ABSTRACT:
A step-up rectifier circuit includes first and second input terminals for applying AC outputs of opposite polarities, a third input terminal connected between the first and second input terminals, a plurality of rectifier elements connected between the third input terminal and a first output terminal, a plurality of output capacitors connected parallel to the rectifier elements, a second output terminal connected to a node between said output capacitors, a plurality of first capacitors connected between nodes between those of said rectifying elements located between the first output terminal and the second output terminal and a plurality of second capacitors connected between nodes between those of the rectifying elements which are between the second output terminal and the third input terminal, wherein the ratio between the capacitance of the first capacitors and the second capacitors is defined such that the ratio between the output voltages at individual output terminals can be made constant, regardless of whether they are loaded or unloaded.
