Disclosed is 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. 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 transformer 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, and 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.提供一種使輸出電壓之頻率提高,而即使輸出之變壓器(transformer)小型化,使用者亦能得到將輸出電壓充足地變成體感之電位治療器。控制電路7,各自將頻率5.4kHz之交流信號輸出至交流輸出端子7a,週期為10~200mS之脈衝信號輸出至脈衝輸出端子7b。輸出變壓器15,將5.4kHz之載波以週期為10~200mS之脈衝信號調變後之調變波,施加至輸出變壓器25之1次側。在輸出變壓器25之2次側之端子25c和抽頭(Tap)端子25d之間產生的交流電壓,藉由二極體27整流,在電容之非接地端子上,產生負的直流高電壓。將脈衝調變過之4.5kHZ之高電壓重疊在此負的直流高電壓之輸出電壓,從高電壓輸出端子33被輸出。1‧‧‧電位治療器3‧‧‧電源插頭5‧‧‧電源電路7‧‧‧控制電路9‧‧‧操作面板11‧‧‧電容13‧‧‧二極體15‧‧‧輸出電晶體17,19,21‧‧‧電阻23‧‧‧電容25‧‧‧輸出變壓器27‧‧‧整流二極體29‧‧‧電容31‧‧‧電阻33‧‧‧高壓輸出端子
