A Modified Quadratic Boost Converter with Continuous Input Current for PV Applications

This study presents a high-gain quadratic DC-DC converter designed to deliver substantial voltage amplification. Eliminating the transformer and having a common ground between input and output has resulted in a smaller size and increased versatility. Furthermore, the converter has a continuous input current, making it suitable for PV applications. The paper develops equations to describe the converter, compares ideal and non-ideal conditions, and investigates non-ideal voltage gain, losses, and efficiency. Simulations are run to validate the derived equations, and the findings are presented.
