Simple and advanced methods for calculating six-pulse diode rectifier line-side harmonics

Abstract

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 measurements of a real application and convincing results are achieved concluding that the proposed methods can be used.
