ABSTRACT:
A control circuit for supplying power to a piezoceramic coupler includes a controllable oscillator for supplying an output signal having the resonance frequency of the piezoceramic coupler and an amplitude control circuit to control the amplitude of the output signal of the piezoceramic coupler. Switching devices are also included to control interruption of the application of the drive signal to the piezoceramic coupler.
