Abstract: This paper proposes a step-by-step procedure for designing the LCL filter of a front-end three-phase active rectifier. The primary goal is to reduce the switching frequency ripple at a reasonable cost, while at the same time achieving a high-performance front-end rectifier (as characterized by a rapid dynamic response and good stability margin). An example LCL filter design is report…
This paper proposes different methods for estimation of the harmonic currents of the six-pulse diode rectifier, which is a very commonly used topology in industry. Both simple and advanced models are compared and the models are put into a context of practical use for calculating the harmonic distortion in a typical industrial application. Finally, the different models are compared to measuremen…
