INVESTIGATION OF HIGH SPEED INDUCTION MOTOR DRIVE OPERATING IN HOUSEHOLD APPLIANCES
Journal Title: Power Electronics and Drives - Year 2016, Vol 1, Issue 1
Abstract
Background: The paper presents conclusions which are results of research on the use of high-speed drives operating in household appliances. The solutions that use three-phase or two-phase induction motors were taken into consideration. The assumed power of motors was up to 1 kW. The article describes the control process of power converters that is characterized by unity power factor and output voltages with the fundamental frequency up to 667 Hz. The requirements for control process were characterized and intelligent solutions were analysed, taking into account power outages, fluctuations, or accidental failures of supply voltage. The control functions of elaborated controller, such as current and speed control, drive start-up and control circuit supply were described. Material and methods: Digital control based on scalar method realized in FPGA EP2C20F484 system. Results: Measurements of HS drive reactions on DC-link voltage changes. Conclusions: Elaborated drive meets the economical recuirements. The resitance to voltage source fauts and the limitation of number of sensors make it possible for the drive to be used in the hausehold appliances.
