Abstract: This paper presents the performance analysis of interior permanent magnet synchronous motor (IPMSM) fed from improved power quality converter–inverter system as a variable speed drive for air-conditioning (Air-Con). The improved power quality converter (IPQC) makes the input power factor unity and also reduces the total harmonic distortion (THD) of input supply current. This converter consists of two uncontrolled unidirectional and two bi-directional switches. It provides constant DC-link voltage during transient and steady state conditions. This converter has high efficiency as only two switches conduct at a time and IPMSM also offers high efficiency as compared to other electric motors. The proposed drive system is an appropriate solution for energy conservation in the AC distribution system, in the motor and in the compressor of Air-Con. The detailed model and the simulated results of the proposed drive system are presented to demonstrate the features of improved power quality and energy conservation.
