Abstract

This paper presents the design and implementation of an Uninterruptible DC-powered boost differential inverter with a sensor-less Changeover system. The systems design was developed using solar panels, bidirectional converter current linked battery banks, and a single-staged DC/AC Converter. The system was designed, modeled, and simulated using MATLAB/Simulink software before its implementation. The properties exhibited by the system include: Single stage input voltage transformation and amplification without a power transformer, lightweight sensor-less and relay-less automatic changeover, and a simplified feedback system. The simulation results show that the system gives a pure sine voltage and current waveforms, total harmonic distortion (THD) of 1.25%, efficiency of 94.4%, relatively fast dynamic response and 1 kilowatt power rating. The specific target areas of applications are: in medical paraphernalia where pure sine waveforms are needed, homes, and medium scale industries.
