摘　　要：A novel and simple ifrea! control algorithm using digital signal processor （DSP） has been proposed and realized for a three phase shunt active filter （SAF）. The simulation and prototype construction of SAF is conducted to compensate the reactive power and harmonics in a distribution system. The major feature of the proposed ifreal algorithm is that it does not require unit vector templates and any transformations for the reference current genera- tion of SAF. This reduces the computational complexity and makes the control flexible and faster. The simulation is conducted in MATLAB/SIMULINK while DSP TMS320LF2407 is employed in the digital implementation of hysteresis current control （HCC） for experimentation. The hardware results correlate with the simulation results in reducing the total harmonic distortion （THD） of the source current and achieving unity power factor.A novel and simple ifrea! control algorithm using digital signal processor （DSP） has been proposed and realized for a three phase shunt active filter （SAF）.
