Solar-Based Boost Differential Single Phase Inverter

CU Eya, MU Agu

Abstract


This paper depicts about a power conversion circuit of a Pulse-width modulated (PMW) voltage source inverter known as a Solar-based boost differential single phase inverter. The total harmonic distortion of 67.12% found in an open loop Solar-based boost differential inverter is reduced down to 22.37% in closed loop system with the aid of Proportional –integral-Differential (PID) voltage controller. The transient stage of the proposed system takes conical shape before it reaches its steady state.   The core characteristics of this type of inverter are:  it engenders an ac output voltage that is greater than the dc voltage which is not obtained in conventional inverter, it trims down the many stages of power conversions found in other boost converters to one stage, it mitigates the ripple contents of the input voltage and current concurrently and finally, it is portable. This research also shows the disparity between the simulated results of open loop and closed loop of boost differential inverter systems. The dc power source is photovoltaic cell. The maximum power point tracker is in-cooperated in capturing the maximum power from the sun. The proposed topic has its applications in homes, offices and more in industries.
