Analysis of a PWM boost inverter for solar home application

Abstract

This thesis analyzes the procedural approach and benefits of applying optimization techniques to the design of a boost dc-ac converter with solar cell as an input. The analysis is performed based on the particular l2V DC to 230 V AC conversion for home applications. A traditional design methodology is the use of buck inverter. One of the characteristics of the most classical inverter is that it produces an AC output instantaneous voltage always lower than the DC input voltage. Thus, if an output voltage higher than the input one is needed, a boost dc-dc converter must be used between the DC source and the inverter. It is less complex, lower cost and provides higher power conversion efficiencies. This technique allows the P.W.M. voltage source inverter to become a new feasible solution for solar home application.
