Abstract(in English) | The authors investigated the control of welding current with a frequency-controlled inverter power supply. Welding current control requires precision sensing of inverter current, which can reach 10kA. The current transformer and Hall effect devices commonly used in the industry do not offer the needed performance. The authors investigated the use of a shunt-type current sensor, using the simplest RI drop method to detect current. This paper discusses the investigation of the extent to which sensor inductance can be cancelled out using the shunt-type current sensor. Results indicate that the inductance component can be cancelled out, making non-inductive operation possible. A current sensor was prototyped and used in a frequency-controlled inverter power supply, demonstrating that welding current control is possible. |
