: This paper proposes an optimal design method for Active power filter set at normal supply voltage, to satisfy the requirements of harmonic filtering. Optimization modal for Active power filter is constructed. The PSO algorithm was developed to find optimal solution for the design of Active filter. This filter is applied to engineering laboratories and other R&D departments, Industries where single phase rectifiers are used which involves harmonic problems indicate the practicality of the proposed design method though at base level.
