modern high current industrial applications power electronic converters like 6 pulse and 12 pulse controlled converters are used. In a power system transient operation of generators will effect respective changes in source inductance of the total system this would in turn cause delta changes in firing angle of the converter in operation. This paper mainly focuses on the modelling of 12 pulse converter and to find the changes in firing angle of converter to evaluate range of operation for a set of source inductance and closed loop control of 12 pulse converter system through MATLAB/Simulink software. The effect of source inductance on the operation for 12 pulse converter is analysed. The different combinations of firing angles for converter is stated for which the converter can appropriately operate within a satisfied region with respect to the Application. A High Current Electro-plating application is considered which uses 12 pulse converter.
