Design and performance analysis of different current control strategies of voltage source inverter

This paper presents different current control techniques described in literature for three phase voltage source inverters, which can be classified into two main categories; Linear control, Non-linear control. Limitations of linear controllers have been discussed and design methodology for implementing the non-linear controllers such as Hysteresis control, Sliding mode control, Ramp comparison control for three phase voltage source inverter feeding RLE load have been presented with an example. The different current control techniques have been simulated using matlab simulink. The simulation results along with the comparative analysis on the performance of different control techniques have also been presented.
