<p><P>PROBLEM TO BE SOLVED: To provide a diode reductant circuit that is formed by connecting a plurality of diodes in series and can keep continuity in an entire circuit and continue the operation of a unit as a whole even if one or two or more diodes among them are damaged and released. <P>SOLUTION: The reductant circuit includes a voltage control switching component wherein one serial diode or two or more diodes are set as one set and respective bypass circuits connected in parallel to the respective diode sets are connected with the corresponding diode sets, and a detection circuit wherein a constant-voltage element and a blown-out circuit are connected in series and they are connected with the diode sets in parallel. An intermediate part between the constant-voltage element and the blown-out circuit of the detection circuit is connected with a controlling part of the voltage driving switching component, and the voltage control switching component is energized by increasing the resistance of the diode through the control unit, thereby detouring a current to flow to the diode set to the voltage control switching component. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
