A Hysteretic Current Controller for Active Power Filter (APF) with Constant Frequency

Advanced Materials Research, 2012
In accordance with the advantage of conventional hysteresis current control method, this paper advances a novel control method for APF. In conventional hysteresis current control, the hysteresis band (HB) is fixed and actual compensating current is limited in a fixed HB. Firstly, the connection between HB and switching frequency must be found correctly.

Active power filter (APF) for mitigation of power quality issues in grid integration of wind and photovoltaic energy conversion system

Renewable and Sustainable Energy Reviews, 2017
The deep integration of renewable energy resources, including solar photovoltaic (PV) and wind turbine (WT) energy, mainly depend on the inexpensive technological improvement of global emissions and the precise techniques for power quality. Grid-connected inverters act as key components in distributed generation systems for cutting-edge technology. The
