Disclosed is that the phases are inputted to the two primary coils alternate normal and reverse in 180 different from the two systems of sinusoidal half wave output step-up transformer to each other, it is possible to obtain a high pressure of a living body the applied AC from the secondary side It provides the alternating potential therapy equipment. A sine low frequency signal from the sinusoidal low-frequency generator 1 is added to the primary coil, while the phase to obtain a half-sine signals of the 180 two different strains from each other, two strains obtained from the high frequency pulse generator 3 of the pulse width modulation circuit 2 and the high frequency pulses, as well as get-width-modulation already high frequency pulse of equal voltage two systems, and by controlling switching of two switching elements Q to each other, respectively, and demodulates the respective pulse outputs to each other, as well as phase get a half-sine demodulated output of 180 different two systems each other, the peak value ratio between the positive and negative voltages of the high-pressure sine wave alternating current generated in the secondary coil by the positive voltage bleeder circuit 5 is a one-to-3 exchanges and I form of the organism applied.BACKGROUND.【課題】位相が互いに180°異なる2系統の正弦半波出力を昇圧トランスにおける二つの1次コイルに交互正逆に入力することで、その2次側から高圧の生体印加交流を得ることができる交流電位治療器を提供する。【解決手段】正弦低周波発生回路1からの正弦低周波信号を1次コイルに加え、位相が互いに180°異なる2系統の正弦半波信号を得る一方、高周波パルス発生回路3から得た2系統の高周波パルスをパルス幅変調回路2により、等電圧2系統の幅変調済高周波パルスを得ると共に、二つのスイッチング素子Qをそれぞれ各別にスイッチング制御することで、これら各パルス出力を各別に復調し、位相が互いに180°異なる2系統の正弦半波復調済出力を得ると共に、2次コイルに発生した高圧正弦波交流を正電圧ブリーダ回路5により正電圧と負電圧との波高値比率が1対3の生体印加交流となす。【選択図】図1
