The high-power ultrasonic pulse generator uses four high-power IGBT devices and their corresponding absorption freewheeling elements to form a half bridge inverter main circuit. The output circuit then transmits this oscillating electrical energy to the transducer array via an output transformer, converting it into mechanical energy acting on the load. The protection system consists of over current protection and over temperature protection, which can suppress output and ensure power circuit safety when power load short circuits create over current or overheating due to poor heat dissipation conditions.
The high-power ultrasonic pulse generator consists of a casing and unit circuits for rectification, inversion, output, control and protection. The rectification unit provides DC power for the inverter and control unit. Each route of the inverter unit consists of a switching tube, a freewheeling element and an absorption element, and its output is connected to an output unit; The output unit consists of an output transformer, a transducer matching element, and a transducer array. The transducer matching element is connected in series with the transducer array and then with the secondary side of the output transformer; The control unit consists of a controlled high frequency oscillator whose output is connected to the input of a switching tube in the inverter unit; The protection unit consists of an overheat over current protection circuit.
