High Power Ultrasonic Generator Variable Frequency 3000W Ultrasonic Industrial Cleaning Generators

In the bridge type power amplifier inverter circuit, the 2000W high-power ultrasonic generator usually uses high-power three stage transistors and IGBT (insulated three bipolar power transistor) as the final stage power amplifier circuit. Ultrasonic has high energy. The oscillation and driving circuit outputs control signals to the power switch in the bridge power amplifier inverter circuit; The bridge power amplifier inverter circuit is connected to the transducer through the output matching circuit, so that the ultrasonic transducer converts the electromagnetic energy into ultrasonic.

The 2000W high-power ultrasonic generator forms a microcontroller power regulation system, where the microcontroller is commonly referred to as a single-chip microcomputer, microcontroller, or embedded microcontroller. In this embodiment, a half bridge inverter power supply is used, and the monotonic relationship between the current of the input half bridge inverter circuit, the amplitude and frequency of the transducer vibration system, and the variation of the load is measured and analyzed to find the one-to-one correspondence between the current of the input half bridge inverter circuit, the amplitude of the transducer vibration system, and the frequency of the ultrasonic generator. When the transducer is in a resonant state, the amplitude is maximum, and the current input to the half bridge inverter circuit is also maximum. That is to say, as long as the maximum current of the input half bridge inverter circuit is searched, the resonance frequency point is also found. Therefore, in this embodiment, a single-chip microcomputer frequency automatic tracking system is formed, which adopts a frequency conversion search method to maintain the maximum current of the input half bridge inverter circuit, thereby ensuring that the transducer always works in a resonant state.

This power control is achieved by adjusting the amplitude, thereby ensuring the stability and safety of process control. The power LED display screen displays the selected gear.
