15khz 1800W Ultrasonic Welding Transducer Genertor With Booster And Flange And Steel Horn for Welding Machine

The 1800W 15KHZ/20KHZ ultrasonic welding power generator is a relatively mature welding method at present. ultrasonic welding forms an ultrasonic wave that can resonate through impedance matching. The molten material is melted through the transducer components and workpiece for welding, which requires high requirements for the ultrasonic welding power supply. The output power of the ultrasonic power supply directly affects the quality and efficiency of ultrasonic welding.

The 1800W 15KHZ/20KHZ ultrasonic welding power generator is the existing ultrasonic welding power supply, which is mostly low power, and this low power ultrasonic power supply has gradually failed to meet the needs of the industry. However, when using high power for welding, the internal interference is easy to occur through high current, leading to power instability, equipment alarm and other phenomena. Therefore, It is necessary to develop a stable high-power ultrasonic welding power supply.

The technical scheme adopted by the 1800W 15KHZ/20KHZ ultrasonic welding power generator is to provide a ultrasonic welding power supply, including a controller, IGBT drive board, soft starter, rectifier, filter board, IGBT inverter and surge absorption board. The input end of the soft starter is connected with an AC power supply. The output end of the soft starter, rectifier, filter board and IGBT inverter are connected in turn. The controller The IGBT driver board and IGBT inverter are sequentially connected, and the output end of the IGBT inverter is connected to the transducer. The surge absorption board is connected to the IGBT inverter, and the surge absorption board is used for circuit protection of the IGBT inverter. The IGBT inverter is fixed on a metal plate, and there is a copper bar layered structure on the IGBT inverter, The filter plate and surge absorption plate are respectively arranged in the copper bar layered structure from top to bottom.
