Start year: 2002

Summary: This project aims to break the major barriers to the commercial production of efficient refrigerators and air conditioners by developing a high efficiency low cost low noise variable speed compressor drive. High performance PM motors, power electronic fault tolerant converters/inverters, and intelligent algorithms for motor control and temperature control will be developed to meet the specific requirements of compressor drives in collaboration with Kirby Refrigeration. The new technology will contribute to the reduction of CO2 greenhouse gas emission by reducing the energy consumption of refrigerators and air conditioners and once commercialised will greatly enhance the competitiveness of Australian industry in the world market.
