A MPPT control method for full soft-switching high step-up current-fed DC-DC converter

This paper is focused on analysis of maximum power point tracking control system for soft-switching high step-up current-fed DC-DC converter. Short review of common tracking methods is given. Closed loop control system is developed. The system behavior in normal and transient modes is analyzed based on the simulation data. A simulation result proves high tracking performance and ability to work in case of step and slope changes of solar panel irradiation. Possible modifications of the algorithm and future work are described.
