Multi-function three-phase active power filter
A new multi-function shunt active filter has been successfully implemented. The proposed decoupler and cascade controller provide a simple solution to power factor correction, reduction of harmonics loads and load balancing. The mathematical burden of resolving the load current to fundamental and harmonics is not required. The decoupler and controller can easily be implemented using low-cost analogue devices.
