Abstract

PURPOSE:To produce the intensive magnetic force line pulses of N and S poles with a single coil by supplying the currents reverse to each other alternately to a magnetic flux pulse generating coil via a pair of thyristor circuits which work alternately on the electric charge of a capacitor. CONSTITUTION:A capacitor C1 is charged from a plus electrode of a power supply B1 through a resistance R1, and this charged electric charge is supplied to a magnetic flux line pulse generating coil L from a point (m). At the same time, a thyristor SCR1 conducts at a point (n). Then a magnetic force line of N pole is produced to the coil L by a current of the SCR1. A capacitor C2 is charged from the plus electrode of a power supply B2 through a resistance R2. This charged electric charge is supplied to the coil L from the point (n). At the same time, the electric charge is discharged at the point (m) through a thyristor SCR2. Thus a magnetic force line of S pole is produced to the coil L. Then the gate signals are applied to gate electrodes of both thyristors SCR1 and SCR2 to make these electrodes conduct alternately. Thus the current pulses are produced to generate the magnetic force lines of N and S directions alternately to the coil L.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for generating magnetic flux pulses with north and south poles using a single coil.

When using the magnetic flux pulse generator for diseased areas or for cell activation, the magnetic field lines should be set at the N pole or the It is desirable that S poles occur alternately.

Although it is easy to generate N-pole and S-pole magnetic lines of force in a single coil by using a transistor,
It is not suitable for use with large currents and requires the use of reeds and scissors.

The present invention uses a thyristor to alternately send large current pulses in opposite directions to a single coil, thereby alternately generating strong N-pole and S-pole magnetic field line pulses.

That is, in the present invention, current is supplied from two insulated DC power sources to a charging/discharging circuit each having a time constant, and the magnetic flux is transferred through two sets of thyristor circuits that alternately operate the charges of capacitors in the charging/discharging circuit. The gist of the present invention is a single-coil NS magnetic flux pulse generator, characterized in that currents in opposite directions are alternately supplied to the pulse-generating coil, and the single coil generates positive and negative magnetic field line pulses. It is something.

Next, the present invention will be explained according to illustrated embodiments.

In the circuit shown in Fig. 1, capacitor C1 is charged from the positive pole of power supply B through resistor R□, and the charge of the charged capacitor C1 is supplied from point m to coil L for generating magnetic flux line pulses. Along with n-point thyristor SC
Electrify R□. The current generates N-pole magnetic lines of force in the magnetic flux line pulse generating coil. After a certain period of time from the energization, capacitor C2 is charged from the positive pole of power supply B2 through resistor R2, and the charge of the charged capacitor C2 is supplied from point n to the magnetic flux line pulse generation coil, and from point m through thyristor 5CR2. By discharging, a current flows in the magnetic flux line pulse generating coil in the opposite direction to that described above, and thus magnetic lines of magnetic force of the south pole are generated.

Therefore, the gate signal X1 as shown in FIG.
By giving y, the thyristor SCR□ and the thyristor 5CR2 are alternately brought into conduction state, and a current pulse N%S as shown in Fig. 3 is generated, and this current causes the magnetic field line pulse generation coil to move in the N direction. Lines of magnetic force are generated in the S direction and the S direction.

The circuit shown in FIG. 4 is an application example for creating two sets of isolated DC power supplies. AC power supply AC, state law side P of Citrans T
A commercial alternating current is supplied to the secondary side Q, and the current transformed from the secondary side Q is full-wave rectified by a rectifier A□ via a resistor R, and further smoothed by a capacitor C3. This smoothed current is charged to the capacitor C□ via the charging series resistor R□. The charge of this charged capacitor C□ flows from point m through the magnetic field pulse generating coil L and from point n to Cyrisk SCR□.

The current generates magnetic lines of force in the N direction in the magnetic line pulse generating coil.

Next, the current is supplied directly from the alternating current power supply AC to the rectifier A2 for full-wave rectification, and further smoothed by the capacitor C4.

This smoothed current is charged to the capacitor C2 via the series charging resistor R2, and the charge of the charged capacitor C2 is n
Electricity is applied from point m to the resistor 5CR2 via the magnetic field pulse generating coil L. Due to the current, lines of magnetic force S are generated in the coil L for generating magnetic line of force pulses in a direction opposite to that described above.

Therefore, by applying the gate signals XsV of the thyristor SCR□ and the thyristor 5CR2 at different times as shown in FIG. A current flows through the magnet, and as a result, lines of magnetic flux in opposite directions of north and south poles are generated alternately.

The circuit in Figure 5 is an example of a wiring diagram when a voltage twice the traffic power supply voltage is required, and the circuit is a transformer T.
The ratio between the state law side P and the secondary side Q is doubled, and it is rectified and used.

Further, the AC power supply AC is directly connected to the diode D2 to perform voltage double rectification to obtain a DC voltage twice the AC power supply voltage.
