The book is included by the basic concepts about solar energy, transformerless inverter, charge pump circuit, and fuzzy logic controller. The students and learners will able to understand the energy generation from solar irradiance and without the transformer, how it will work. Mostly targeted audience or readers will be from an academic background like a diploma, undergraduate and postgraduate. It will help the learner with efficient control strategies of the transformerless inverter and charge pump circuit where fuzzy logic control is adopted.
