In this paper, a mathematical model of single phase active power filter is derived. A method of calculating parameter for voltage-type active power filter compensating reactive power current and harmonic currents generated by single phase rectifier is presented. The computer simulation for single phase voltage-type active power filter is studied. The results show that both of the reactive power and harmonics can be suppressed effectively with active power filter.
