The Variable Speed Air Conditioner (VSAC) is a large domestic distorting load. We investigate the impact of a large number of VSACs 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.

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.
