| Abstract: | 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 0.5A±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. |
