A Novel Fuzzy Variable-Band Hysteresis Current Controller For Shunt Active Power Filters
نویسنده
چکیده
This paper presents a novel fuzzy control scheme applied to shunt active power filters for harmonic and reactive power compensation. A TSK type fuzzy logic controller is proposed for APF reference current generation. To control the maximum switching frequency of the converter within limit a novel fuzzy hysteresis band current controller is used. The band height, based on fuzzy control principle is changed with the value of supply voltage and slope of reference current. Keywords—active power filter, nonlinear load, TSK type fuzzy controller, harmonics, indirect current control scheme

متن کاملApplicability improvement and hysteresis current control method simplification in shunt active filters
Hysteresis current control method is vastly used in PWM inverters because of simplicity in performance, fast control response and good ability in limiting peak current. However, switching frequency in hysteresis current control method with fixed bandwidth has large variation during a cycle and therefore causes non-optimal current ripple generation in output current. One of basic problems in imp...
