摘要
A PEMF therapy system uses a bi-phasic coil PEMF transducer for generating PEMF stimulation signals. The coil has a 'bi-phasic' operation, such that current flows through it in two directions. A drive circuit recovers the flyback energy from the transducer coil and dumps voltage to an energy recovery capacitance circuit. The transducer is thereby energized and de-energized to provide the electromagnetic field. The same concepts are applicable to series-connected coils. The transducer is especially suited for high frequency operation.
