PROBLEM TO BE SOLVED: To provide an electrical potential therapeutic device which may output electrical potential capable of being sufficiently sensed by a user with his body even if a frequency of output voltage is increased and an output transformer is downsized.SOLUTION: A control circuit 7 respectively outputs AC signal having a frequency of 5.4 kHZ to an AC output terminal 7a and pulse signal having a cycle of 10 to 200 ms to a pulse output terminal 7b. An output transistor 15 applies modulated wave which is created by modulating a carrier wave of 5.4 kHz with the pulse signal having cycle of 10 to 200 mS, to the primary side of an output transformer 25. An AC voltage generated between a secondary terminal 25c and a tap-out terminal 25d of the output transformer 25, is rectified by a diode 27, a high negative DC voltage is generated at the non-ground side terminal of a capacitor. Outputted from a high voltage output terminal 33 is an output voltage in which a pulse modulated high voltage of 4.5 kHz is superimposed on the high negative DC voltage.COPYRIGHT: (C)2015,JPO&INPIT【課題】出力電圧の周波数を高くして出力トランスを小型化しても利用者が出力電位を体感として十分に得られる電位治療器を提供する。【解決手段】制御回路7は、周波数が5.4kHZの交流信号を交流出力端子7a、周期が10~200mSのパルス信号をパルス出力端子7bへそれぞれ出力する。出力トランジスタ15は、5.4kHzの搬送波を周期が10~200mSのパルス信号で変調した変調波を出力トランス25の1次側に印加する。出力トランス25の2次側の端子25cとタップ端子25dとの間に生じる交流電圧は、ダイオード27により整流され、コンデンサの非接地側端子には、負の直流高電圧が発生する。この負の直流高電圧にパルス変調された4.5kHzの高電圧が重畳された出力電圧が高圧出力端子33から出力される。【選択図】図1
