نویسندگان
چکیده
-A new control method for single-phase shunt active power filter (APF) is proposed. It integrates the DC bus voltage control and active power filter command current generation, according to the periodicity of source current and energy balance concept. The instantaneous harmonic compensation and linear DC bus voltage control are achieved, without complicated and involved control logic, by using cycle discrete control technique to DC bus voltage. A mathematical model of the scheme is developed. Detailed analysis and simulation in the PSCAD/EMTDC environment are presented. A laboratory prototype of this APF is developed to validate the result. Both of simulation and experimental results show the good behavior of this type of APF. Key-Words:-Active power filter, Discrete control, Harmonic and Reactive power, PWM.
