Research output: Contribution to journalArticlepeer-review


A voltage changer for the power supply of an ultrasonic piezoelectric transducer is designed on the basis of a resonance inverter. The output filter designed on the basis of a series-resonant circuit with parallel and series compensation ensures matching of the changer to the load. The changer ensures a load current of 0.5 A ± 10% within a wide range of the load resistance (from 50 to 400 Ω) at an input voltage of 220 V ± 15% with automatic tuning to the frequency of the load mechanical resonance. The changer output power is 100 W, and the output current is a sinusoid with a frequency of 22 ± 2 kHz.
