The main drawback of Shunt Hybrid Filters is the need of leading current injection. This paper describes a strategy to reduce the leading current in a three phase four wires LC coupled parallel hybrid filter for harmonics cancellation. Simulation and experimental results are given to show the behaviour of the system.
