Abstract: The thermal therapy device comprises an inverter circuit connected to the primary side of a transformer, a series resonance circuit connected to the secondary side of the transformer and including a magnetic field generation coil and a resonance controller, and a controller for determining the resonance frequency based on the secondary current. The controller has a measurement mode and an operation mode which are alternately repeated. During the measurement mode the resonance frequency of the series resonance circuit is measured, while during the operation mode a drive signal of said measured resonance frequency is supplied from the controller to the inverter circuit.
