    Full Bridge LLC Resonant Converter Design for Photovoltaic Applications
    (Ieee, 2022) Kucuk, Tufan Volkan; Oncu, Selim
    In this study, full bridge LLC resonant converter is simulated for photovoltaic (PV) system. The maximum power point tracking (MPPT) algorithm perturb and observe (P&O) is used to track the maximum power point (MPP) in the PV system at different irradiance values. P&O algorithm is adapted with phase shift modulation and made suitable for resonant converter. The proposed system is simulated with PSIM under three different irradiance values. It can be seen from the simulation results that MPPT and soft switching conditions have been successfully achieved in all three irradiance values.

    Wind Energy Conversion System With PDM Controlled Converter
    (Ieee, 2021) Kucuk, Tufan Volkan; Oncu, Selim
    In this study, the variable speed wind energy conversion system using permanent magnet synchronous generator is operated at the maximum power point at different wind speeds. The designed system consists of a wind turbine, a permanent magnet generator, three phase rectifier, a series resonant converter and a load. Operation at the resonant frequency for different power values has been made possible by using the pulse density modulation (PDM) method. System operates at the resonant frequency. The power switches operate in soft switching conditions. Results show that zero current switching conditions can be achieved for different wind speeds and maximum power point (MPP) of the wind generator is tracked with soft switching.
