Output power of ultrasonic generator
When the access voltage of the ultrasonic generator changes, the output power of the generator also changes. The mechanical vibration of the ultrasonic transducer will be unstable, resulting in poor working effect. Therefore, it is necessary to stabilize the output power and adjust the power amplifier through the power feedback signal to make the power amplification stable.
The transducer works at the resonance frequency point with the highest efficiency and stability.
The resonant frequency of the transducer will change due to assembly and aging. If the changed frequency is only drift, the frequency tracking signal can control the generator, so that the frequency of the signal generator can track the resonant frequency point of the transducer within a certain range, so that the generator can work in the optimal state.
