Abstract

The variable speed air conditioner (VSAC) is a large domestic distorting load. We investigate the impact of a large number of VSAC´s on domestic harmonic levels. We present a general method to build a harmonic numerical model of a passive filtered rectifier supplied by a distorted voltage; a statistical method to assess the total harmonic currents produced by a large number of units running at various power levels and supplied by various distorted voltages. These two methods are applied to a rectifier used by many VSACS. We also present results for two other rectifiers
