Active power filters: A comparative analysis of current control techniques

This paper presents a comparative analysis between different control techniques for voltage source inverters (VSI), based on shunt active power filter. The main purpose is to study the behaviour of each technique for a given reference current. In addition, some simulations are presented in ATP. The reference signals tracking for different current control techniques and different converter topologies is shown by these simulations. The control techniques are compared based on some criteria such as maximum steady state error and effective error of the current generated by the inverter.
