3000W Industrial Ultrasonic Bath Generator For Ultrasonic Immersible Transducer Pack

The replacement of high-power ultrasonic cleaning equipment is mainly marked by the update of the ultrasonic power supply. With the development of high-power electronic devices, high-power ultrasonic pulse generator has obtained superior performance in the new generation of development. At present, the ultrasonic cleaning power supply is mainly based on the switching power supply circuit.

 

 

 

The high-power ultrasonic pulse generator uses four high-power IGBT devices and their corresponding absorbing freewheeling components to form a half-bridge inverter main circuit. The output circuit transmits the oscillating electric energy to the transducer array through the output transformer and converts it into mechanical energy to act on the load. The protection system is composed of overcurrent protection and overheat protection. When the power load short circuit produces overcurrent or overheat due to poor heat dissipation conditions, it can inhibit the output and ensure the safety of the power circuit.

 

 

 

The high-power ultrasonic pulse generator is composed of the shell and circuits of rectifier, inverter, output, control and protection units. The rectifier unit provides DC power for the inverter and control unit. Each line of the inverter unit is composed of switch tubes, continuous current elements and absorption elements, and its output is connected to the output unit; The output unit is composed of output transformer, transducer matching element and transducer array. The transducer matching element is connected in series with the transducer array and then connected in series with the secondary side of the output transformer; The control unit is composed of a controlled high-frequency oscillator whose output is connected with the input of the switch in the inverter unit; The protection unit is composed of overheat and overcurrent protection circuit.
