In the fiercely competitive welding market, there is an increasing preference for lightweight and cost-effective welding equipment. Increasing the operating frequency of the welding machine will greatly reduce the overall weight and volume of the machine, significantly reduce the loss of copper, iron and other materials and energy, and improve the dynamic response time of the power supply by more than two orders of magnitude, which can bring about an improvement in welding performance. 

Taking into account the development trend of high-frequency welding machines, based on the previous generation technology, Changde Microelectronics has optimized the IGBT products applied in the welding machine field, significantly reducing the switching losses of IGBT devices and improving the switching speed of devices. Customers using Changde Microelectronics' IGBT can significantly increase the switching frequency of welding machines, reduce the size of welding machines, lower production costs, and improve the overall cost-effectiveness of welding machines under the same output power conditions. 

The MOS products in the auxiliary power supply of the welding machine have optimized the cell and terminal design, with the advantages of strong impact resistance, good reliability, and high cost-effectiveness.
