ABSTRACT:
A power generator is provided to drive an high power ultrasonic transducer at its resonant frequency even under changing conditions cause by e.g. load fluctuations, aging or heating. The power generator uses a variable-controlled oscillator driving a power amplifier; a three winding transformer has one winding coupled to the transducer, one winding coupled to the output of the power amplifier and the third winding coupled to a phase measuring means. The output of the phase measuring means is fed back to the variable-controlled oscillator.
