  • High efficiency pulsed electromagnetic field (PEMF) stimulation therapy method and system
    Patent number: 5743844
    Abstract: A PEMF stimulation therapy system uses a PEMF transducer coil for generating PEMF stimulation signals and includes a single-winding transducer coil. A drive circuit recovers flyback energy from the single-winding transducer coil and dumps the voltage to a voltage supply equal to a predetermined high voltage that differs from supply voltage. This permits sequencing the current through the PEMF transducer coil in a positive direction and then negative direction. The result is a PEMF stimulation therapy system that may use a commercially available, low-cost battery for power and that is significantly lighter and more portable than known PEMF stimulation therapy systems.
