1000W 68Khz High Frequency Ultrasonic Generator Driving Box For Cleaning Tank

The frequency tracking of the 68khz high-frequency ultrasonic cleaning power generator uses feedback technology to automatically adjust the switching frequency of the ultrasonic power supply to follow the resonance frequency changes of the ultrasonic vibration system to ensure the normal operation of the vibration system. Therefore, automatic frequency tracking is the key to ensuring the normal operation of power ultrasound systems and has important significance. Real time tracking of changes in the resonant frequency of the transducer and controlling the switch frequency to maintain consistency with the resonant frequency.

The frequency tracking of the ultrasonic power supply of the 68khz high-frequency ultrasonic cleaning power generator often adopts phase-locked frequency tracking and other electrical tracking technologies, which samples and matches the voltage and output current before the network, and feeds back the phase difference and relationship of the output voltage and output current to the power control system. The 68khz high-frequency ultrasonic cleaning power generator requires a method of adjusting the frequency of the ultrasonic power supply to be suitable for systems with different output square wave duty cycles, while improving the system’s anti-interference ability and reducing costs.

The 68khz high-frequency ultrasonic cleaning power generator samples the output current square wave and output voltage square wave to obtain the counting values of the time base counter when the rising and falling edges appear. Through these counting values, the calculation of the midpoint counting values of the high-level pulse of the output current square wave and output voltage square wave is completed, thereby obtaining the phase difference and phase relationship between the output voltage and output current, which can achieve frequency tracking. The method can achieve frequency adjustment without limiting the duty cycle of the output voltage square wave and the output current square wave, while improving the system’s anti-interference ability and reducing the system’s cost.
