| Abstract |
The article presents orginal results of digital analysis and experimental research of the transistor, series, resonant inverter which feeds the group of SANDWICH type piezoelectric ceramic transducer in ultrasonic cleaners. The purpose of the analysis was to determine optimal parameters of resonant inverter circuit, which, in the case of the elements of tuning the generator vibration frequency to the mechanical resonanse frequency of transducers, make it possible to obtain maximum output power, as well as to determine the extreme values of currents and voltages when the untuning of the groups of transducers from resonant, frequency occurs. In the summary we compared the results of digital analysis with experimental results of half-bridge inverter system with MOSFET transistors whose output power is 5kW and operating frequency 26 kHz. |
