ultrasonic transducer 20khz generator circuit

Ultrasonic generator, also known as ultrasonic drive power, electronic box, ultrasonic controller, is an important part of high-power ultrasonic system. The function of ultrasonic generator is to convert the market electricity into high frequency alternating current signal matching with ultrasonic transducer and drive ultrasonic transducer to work. Generally speaking, switching power supply is widely used in high power ultrasonic power supply. Ultrasound power supply is divided into self-excited power supply and its excitation power supply, self-excited power supply is called ultrasonic analog power supply, its excitation power is called ultrasonic generator.

Machine features:

1. Frequency fine-tuning: adjust the frequency so that the ultrasonic transducer always works in the best state, the efficiency reaches the maximum;

2. Automatic frequency following: once the equipment has completed its initial settings, it can work continuously without adjusting the generator;

3. Amplitude control: when the load changes during the transducer operation, it can automatically adjust the driving characteristics to ensure that the vibration head gets a stable amplitude.

4. System protection: When the system works under unsuitable operating environment, the generator will stop working and alarm display to protect the equipment from damage.
