PROBLEM TO BE SOLVED: To provide potential therapy equipment with a simple mechanism where a function of differentiating the value of a potential between the case of a positive potential and the case of negative potential and a function of generating the same potential in both of the cases of the positive potential and the negative potential can be switched. SOLUTION: Two coils for generating high voltage are provided at a transformer. Voltage obtained by full-wave-rectifying voltage generated by a pair of the coils or rectifying the voltage only in the case of positive polarity is generated and voltage generated by the other coil is superimposed to this by anti-phase or in-phase to make the peak level value of the positive potential smaller than or equal to that of the negative potential without changing the voltage of the negative potential. Further, by superimposing voltage obtained by dividing the rectified voltage, this circuit shows a similar effect. COPYRIGHT: (C)2003,JPO
