BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a potential therapy device that performs treatment by applying a high potential to a living body, and more particularly, to a high voltage generator.

Background Art Conventionally, a potential treatment device for generating an electric field around a living body by applying a high voltage to an electrically insulated living body has been known. This dislocation therapy device is recognized for its efficacy in stiff shoulders, headaches, insomnia, chronic constipation and the like by improving the ion balance of the living body or acting on the autonomic nervous system.

Figure 7 illustrates two major states of use of a conventional dislocation therapy device. FIG. 7A shows a state in which the user places the dislocation treatment device 101 in a sitting position. The chair 105 is disposed on the insulating sheet 102 attached to the floor, and the conductive sheet 103 is mounted on the sheet surface. The high voltage cable 104 extending from the energizing sheet 103 is connected to the output terminal of the potential treatment device 101. The user sets the treatment mode, treatment time, treatment voltage, and the like to the operation display panel provided on the upper surface of the potential therapy apparatus 101, and then sits on the chair 105.

FIG. 7B shows a state in which the user lays down and uses the dislocation treatment device 101, and lays the blanket 107 on the insulating sheet 102 laid on the floor, and the center portion of the blanket and the position corresponding to the hip part of the user accurately. The power supply sheet 103 is mounted on the power supply sheet, and the high voltage cable 104 extending from the power supply sheet 103 is connected to the output terminal of the potential treatment device 101. The user sets the treatment mode, treatment time, treatment voltage, etc. with the operation display panel provided on the upper surface of the potential therapy apparatus 101, and then lies on the duvet 107.

In a conventional potential therapy device, an alternating current high voltage and a negative polarity direct current high voltage are also used, but a waveform in which the alternating current high voltage superimposes a negative polarity direct current high voltage has a high therapeutic effect.

Therefore, as a conventional potential therapy device, a direct current high voltage is generated from a voltage variable device such as a high voltage transformer that boosts an AC commercial voltage to generate an AC high voltage, and a slide variable that varies the AC commercial voltage, and an AC voltage added or subtracted by the voltage variable device.

The negative shift is the ratio of the negative peak value of the waveform to the peak-to-peak value of the AC voltage of the potential treatment device (when the AC voltage is Eac, the peak-to-peak value is 2√2 × Eac). In a conventional potential therapy apparatus, the DC component shown in FIG. 9A is set in the range from -50% of 0 to -100% in which the DC component shown in FIG. 9C becomes √2 * Eac.

Returning to FIG. 8A, the AC voltage having an effective value of 9000 V (hereinafter, AC 9000 V) has a maximum amplitude of about 12700 V and a peak-to-peak value (hereinafter, abbreviated as pp value) of about 25400 V for both positive and negative polarities. When negative shift -100% is applied to this AC9000V, it becomes a waveform shown in FIG. 8B.

When the voltage rms value Erms of the waveform of this figure is calculated, it becomes about 15600V, and it is anticipated to produce a very large electric potential and an electric field effect compared with AC9000V.

The transistor drive circuit 14 is a drive circuit that outputs the base signal of the transistor 31. The transistor 31 is a transistor for generating a DC voltage component, and similarly to the transistor 21, a FET or an IGBT may be used. The collector of the transistor 31 is connected to one end of the primary coil 35 of the high voltage transformer 34, and the other end of the primary coil 35 is connected to a direct current 140V supplied from a power supply circuit (not shown). .

One end of the secondary coil 36 of the high voltage transformer 34 is grounded, and the other end thereof is connected to the cathode of the high voltage rectifying diode 37 built in the transformer. The anode of the high voltage rectifier diode 37 is connected to one end of the smoothing capacitor 46 and the secondary coil 26 of the high voltage transformer 24.

FIG. 6 is a circuit diagram for explaining a modification of the high voltage output means 6 in the third embodiment. In FIG. 6, the primary coil 53 of the first high voltage transformer 52 is driven by the transistor bridge output circuit 80. The transistor bridge output circuit 80 consists of four transistors 71, 72, 73, 74. The collectors of the transistors 71 and 72 are connected to the collector power supply 140V together. Emitters of transistors 71 and 72 are connected to collectors of transistors 73 and 74, respectively. The emitters of transistors 73 and 74 are grounded together. One end of the primary coil 53 of the first high voltage transformer 52 is connected to the connection point of the emitter of the transistor 71 and the collector of the transistor 73, and the emitter and transistor 74 of the transistor 72 are connected.

The anode of the high voltage rectifier diode 37 is connected to one end of the capacitor 46 and the other end of the capacitor 46 is grounded. As a result, the negative DC high voltage rectified by the high voltage rectifier diode 37 is smoothed in the capacitor 46.

The negative DC high voltage is superimposed on the AC high voltage output to the secondary coil 54 of the first high voltage transformer 52 and output to the output terminal 7 through the high resistance 48. The voltage dividing resistors 43 and 44 which divide the voltage and feed it back to the control microcomputer 12 are connected to the output terminal 7.
