Abstract
In photovoltaic inverters, transformerless inverter has been emerging trend in recent years. Control of transformerless inverter keeping all other parameters in consideration is a major concern. This paper presents proportional–integral–derivative (PID) and fuzzy-based control strategies for H5 inverter topologies describing their principal functions are uses. Voltage balancing of H5 inverters under various load conditions was observed with the use of PID, fuzzy and fuzzy-PID controllers. Several specific requirements are taken into consideration and subsequently analysed, the simulation model and the results defined effectiveness of the system for various controllers in terms of stability, settling time and harmonic distortions. At the end, the experimental results are introduced, and they confirm the accuracy of propounded control strategies.
