Embodiment Construction
[0016] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0017] refer to figure 1 As shown, one embodiment of the present invention is a submerged arc welding power supply AC and DC square wave controller, the controller includes:
[0018] The main control module is connected to the power input terminal of the IGBT driver module and the controller, and is used to dynamically sample the current current and voltage of the power input terminal, and convert various parameters from the control terminal into control signals, and then transmit them to the IGBT driver Module; through the aforementioned control terminal, the controller can be matched with external equipment, allowing users to set submerged arc welding parameters;
[0019] The IGBT drive module is connected to the inverter module, and is used to isolate and amplify the control signal from the main control module and output it to the inverter module to control the ou...
