Picture Example:

28K Ultrasonic Spot Welding Machine generator, also known as ultrasonic drive power supply, electronic box, ultrasonic controller, is an important part of high-power ultrasonic system. The role of the ultrasonic generator is to convert the mains into a high-frequency ALTERNA signal matched with the ultrasonic transducer and drive the ultrasonic transducer to work. From the perspective of conversion efficiency, high-power ultrasonic power supplies generally adopt the circuit form of switching power supplies. Ultrasonic power supply is divided into self-excited power supply and it excited power supply, self-excited power supply is also known as ultrasonic analog power supply, it is not only a power supply, also known as ultrasonic power generator.

overview:
The 28k Spot Welding Machine power generator adopts other excitation shock circuit structures, and the output power is increased by more than 10% compared with the self-excited shock circuit structure. The ultrasonic amplification circuit adopts a linear amplification circuit and a switching power supply circuit.
Advantages of switching power supply circuits: high conversion efficiency, so high-power ultrasonic power supplies use this form.
Advantages of linear power circuits: There is no strict requirement for circuit matching, allowing the operating frequency to change continuously and rapidly.
principle:
Ultrasonic spot weld generator generators generate signals at a specific frequency (sinusoidal or pulsed) at which the transducer operates.
Ultrasonic Spot Welding Machine typically uses ultrasonic frequencies of 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz, 80KHz, 100KHz or above, which have not yet been widely used.


How to feedback signals:
The ultrasonic power generator has a feedback link, which mainly provides feedback signals in the following two aspects.
1. Output power
When the input voltage of the ultrasonic generator changes, the output power of the generator also changes. This will make the mechanical vibration of the ultrasonic transducer unstable, resulting in poor working results. Therefore, it is necessary to stabilize the output power and adjust the power amplifier accordingly through the power feedback signal to stabilize the power amplifier.
2. Frequency tracking
The sensor operates at a resonant frequency point, has high efficiency and stable operation.
Due to assembly and aging, the resonant frequency of the sensor changes. If the changed frequency is only drift, the change is not large, the frequency tracking signal can control the signal generator, so that the frequency of the signal generator tracks the resonant frequency point of the transducer within a certain range, so that the generator works in a normal state.
