In this paper, a new accurate and comprehensive analytical model of harmonic and interharmonic distortion produced by a single-phase AC/DC diode rectifier (DBR) is presented. Its main and new characteristic is the ability to consider the presence of interharmonics in addition to harmonics in the voltage at the terminals of DBR due to the background voltage. Analytical expressions able to predict DC voltage and AC current in time domain are obtained. Several numerical and experimental tests have been performed, but in this paper only the numerical and experimental validation on a commercial equipment (i.e. CFL lamp) showing very accurate results is reported for space limitations.

Abstract
In this paper, a new accurate and comprehensive analytical model of harmonic and interharmonic distortion produced by a single-phase AC/DC diode rectifier (DBR) is presented. Its main and new characteristic is the ability to consider the presence of interharmonics in addition to harmonics in the voltage at the terminals of DBR due to the background voltage. Analytical expressions able to predict DC voltage and AC current in time domain are obtained. Several numerical and experimental tests have been performed, but in this paper only the numerical and experimental validation on a commercial equipment (i.e. CFL lamp) showing very accurate results is reported for space limitations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
