Implementation of continuous power supply system for domesttic lighting using solar based spwm inverter and diesel generator

In this thesis describe details of fully automatic system for continuous power supply for domestic load .In which solar power, supply mains and diesel generator use as source .System gives output on the predefined priority. First priority is set on solar power , second priority is set on the supply mains and last one is on diesel power. For converting solar DC power in AC power SPWM base voltage source inverter used. For designing SPWM voltage source inverter IGBT bridge used and for generation for SPWM gate pluses reference sine wave compare with triangular wave . Performance of single phase SPWM inverter fed domestic load is described in detail.
