MODELLING OF SOLAR PHOTOVOLTAIC ARRAY FED BRUSHLESS DC MOTOR DRIVE USING ENHANCED DC-DC CONVERTER

摘要

The proposed research involves modeling of solar photovoltaic array fed BLDC Drive using enhanced DC-DC converter. Both step-up and step-down converter, DC-link unit are proposed in this research. The proposed circuit includes modern feed-forward sensing methods for applied potential Sensing, Third harmonic Voltage combination, Terminal Current Sensing, Back-EMF Integration and PWM strategies. For the efficiency improvement reduced number of switches in the proposed circuit makes the scheme more outlay efficient and the motor speed is synchronized by PI controller as a result it is more efficient compared with conventional. The recent techniques based on analysis and values, models are clearly experimented in the research. A Matlab platform and hardware model of two-output output Buck-Boost converter is developed and its concert is analysed for various effective environment.
