Description

technical field

[0001] The present invention relates to the technical field of optical-mechanical-electrical integration, and also relates to power electronics technology, high-frequency inverter technology, digital control technology and automatic control theory and technology, specifically refers to an ARM-based embedded digital multifunctional inverter soft switch Arc welding power supply. Background technique

[0002] At present, in the field of welding power sources, due to the large current and high power required by the process, the traditional welding power sources are mainly silicon rectifier and thyristor rectifier, which are bulky, heavy, low energy consumption, and low efficiency. The reason is that the dynamic and static characteristics are not ideal. Using inverter technology is the best way to solve these problems. First of all, the inverter technology greatly increases the frequency of the power supply, which greatly reduces the volume and quality of the ma...
