Uninterruptible DC-powered Boost Differential Inverter with a Sensor-less Changeover System
Authors: , ,
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
