A method for PWM rectifier line side filter optimization in transient and steady states

The purpose of this paper is to develop, design and test an overall approach to line side filter optimization for the current type PWM controlled active rectifier and to investigate influence of control system to converters performance and filter size (TkVA). For the instantly predominating offline current rectifier control methods, a line side filter optimization algorithm and corresponding computer program was proposed and developed. It uses both complete transient and steady state, characteristics of system, ensuring minimized individual and total harmonic distortion (according to standards) of line current and a good power factor together with minimum costs. Suggested method was numerically verified through the extensive simulations using SIMULINK toolbox of MATLAB software. Final verification came from the implementation on a prototype. Detailed testing was performed and the proposed algorithm showed satisfying performance under different operating conditions. As far as the authors are aware, the novel contribution coming from this paper is in completing the line side filter optimization algorithm taking into account both transient and steady state of system, power supply demands and the power factor restriction for the offline controlled current type AC/DC converter.
