The paper present the model based predictive controller for ripple free, high power active filter (APF) with LCL circuit. The system suppresses LCL resonance and provides control dynamics limited only by circuit parameters. The inverter of an active power filter requires a high PWM switching frequency, therefore high power application has to be realized by using several power modules operating in...
The paper presents the novel control system for a shunt active power filter (APF) connected to an electrical grid via LCL circuit. Such a circuit constitutes 3rd order low pass filter and almost completely attenuates current ripples from PWM, which are the major drawback of APF connected via inductors. Such a solution requires control that overcomes LCL resonance problem and, at the same time, maximizes...
