Abstract :
A new control scheme for the line current detection type active filter (AF) is proposed to improve the current regulation capability based on the digital deadbeat control. The current control scheme is achieved by controlling the intermediate voltage of the inverter output filter so that the AF output current is regulated using the deadbeat control law for the calculation of the pulse width of the PWM inverter. In the proposed scheme, the current regulation performance is improved much better than the conventional one. The control method, mathematical analysis, the simulation results and the experimental results are presented in this paper.
