MAGNETOTHERAPEUTIC UNIT Russian patent published in 1997 - IPC

FIELD: medical equipment, in particular, physiotherapeutic devices. SUBSTANCE: magnetotherapeutic unit generating pulses of attenuating sine-shaped magnetic field has inductor with three windings, three-phase generator, power unit and control unit. Three-phase generator has three similar charging-discharge circuits, each having storage capacitor, discharge switch and related inductor winding. Circuit capacitor is charged by power unit at charging cycle through charging switch and related bypass diode. Discharge of capacitors is performed at discharge cycle by pulses delivered by control unit and having pulse duration sufficient to provide discharge of capacitors. Pulses are supplied to discharge switches at delay of 1/3 of free period in circuit. EFFECT: improved weight, size and power characteristics, wider range of amplitude-frequency characteristics of magnetic field. 1 dwg
