PURPOSE:To take out a plurality of outputs from a single high-voltage transformer and perform the current control the output fed to a specific load, by providing a plurality of rectifier circuits on the secondary side of the single high-voltage transformer, and by controlling the output current of one rectifier circuit of them through the feedback of the output current. CONSTITUTION:On the secondary side of a high-voltage transformer T1, a rectifier circuit comprising a rectifier diode D1 and a smoother capacitor C1 is configured, and from an output 1, an output current I1 is fed to a load Z1. Also, in parallel with this rectifier circuit, another rectifier circuit comprising a rectifier diode D2 and a smoother capacitor C2 is provided, and from an output 2, an output current I2 is fed to a load Z2. Further, a diode D3 is so provided that its forward direction coincides with the charging direction of the capacitor C2, and between a ground and the connection point of the diode D3 and the capacitor C2, a resistor R for sensing the output current I2 of the output 2 is provided connectively, and further, its sensed voltage is used as a controlling feedback voltage. |
