7) High frequency transformer isolated grid connected inverter

• Place: Department of Electronic Systems Engineering (formerly CEDT), Indian Institute of Science, Bangalore, INDIA

• Desciption:

  • Developed a single-phase high-frequency transformer-isolated 250W micro-inverter. The topology consists of a single-phase inverter with single-stage power conversion. The high-frequency transformer is used to provide not only the isolation but also the required gain. Thus, 25-32V DC voltage (can be from solar panel) is directly converted to 230V, 1-phase, 50 Hz AC voltage. The inverter control was based on d-q axis control and implemented in the Cypress PSOC 5LP controller.
