摘要：A device for exciting oscillations in piezoelectric converters especially for ultrasonic use, has a high frequency (HF) generator with a clocked end stage and a transformer. The transformer is designed as a HF stray field type (2) with a high stray inductance, which can be adjusted and tuned to the capacitive load of at least one piezoelectric converter (3). To adjust the inductance, the relative position of at least one primary winding and one secondary winding can be changed. The position of the magnetic core can also be changed relative to them, as well as the relative air-gap.
