    摘要: A multiple step-up rectifier circuit, according to the invention, has a plurality of multiple step-up rectifier circuits, each of which is constituted by a combination of a plurality of diodes connected in series, output capacitors which are connected in parallel with this series circuit of the diodes, and supply capacitors which are charged by the input AC voltages and which supply the voltages to the output capacitors in amounts equal to the discharged voltages thereof. These plurality of multiple step-up rectifier circuits are connected in series, and each of these circuits receives an arbitrary AC voltage and generates a multiple step-up voltage. In these two adjacent circuts, there is the following relation: ##EQU1## where, C.sub.1 is the capacitance of each of the capacitors constituting one of the multiple step-up rectifier circuits; E.sub.1 is the input voltage thereof; I.sub.1 is the value which is obtained by adding the output current of this circuit and all of the output currents of the circuits of the post stage of this circuit; n.sub.1 is the half of the number of supply capacitors of this circuit; C.sub.2 is the capacitance of each of the capacitors constituting the other multiple step-up rectifier circuits; E.sub.2 is the input voltage thereof; I.sub.2 is the value which is derived by adding the output current of the second circuit and all of the output currents of the circuits at the post stage of this circuit; and n.sub.2 is the half of the number of the supply capacitors of the second circuit.
