The paper presents a three-phase parallel active power filter without filter current measurement. Only supply grid voltage sensors, filter capacitor voltage sensor and supply line current sensors are used to provide filterpsila proper operation, aiming to reduce reactive power and line current distortion, caused by a non-linear load. Due to filterpsilas inverter-like topology with known parameters in filter branch, the predictive direct current control (DCC) method has been successfully applied… CONTINUE READING
