Inverter welding machine is a new type of welding power supply. The working principle is as follows: First, power frequency voltage of AC network is converted to DC voltage after being rectified and filtered by the rectifier. Then, after the interchangeable effect of high-power switch electronic components like MOSFET or IGBT, the DC voltage is inverted to AC voltage with frequency ranging from tens of kHz to hundreds kHz.
