This paper presents the development of a constant and wireless controlled DC/AC based boost differential converter with a sensor-less changeover system. The system was computationally designed, modeled, and simulated using MatLab/Simulink software prior to its practical implementation. The designed and simulated system was implemented using solar panels, two directional DC-DC converter current linked battery banks, and a single-staged H-bridge DC/AC converter. The unique properties of the developed system include: one stage input voltage conversion and magnification without the need of a power transformer, wireless turn-on/off scheme, weightless, sensor-less and relay-less automatic voltage changeover, and a simplified feedback system. The Matlab/Simulink simulation results show that the system achieves a pure sine output voltage and current waveform, total harmonic distortion (THD) of 1.22%, efficiency of 94.45%, moderately fast transient response of 1.5 kW. The simulated results were validated with practical experimentation of the system. The definite target areas of utilization of the developed system are: in hospital equipment and remote rural areas.
