Description
Summary:In this paper, a practical solution for suppression of voltage harmonics in high-voltage power supplies is proposed. The solution is based on three single-phase series active-power filters (SAPF) inserted in a common point of a synchronous generator (SG) through an injection transformer. Because of the SAPF position, implementation of low-voltage components enabling higher switching frequencies needed to compensate harmonics with a sufficient level of precision is fully justified. Combined with a sophisticated repetitive control algorithm and using a superior digital signal controller (DSC), an extremely low harmonic distortion in a large frequency span is achieved.
