Abstract

The present research work discuss about a hybrid DC-DC buck converter with QFT controller which is intended to reduce the power component voltage stress. The conventional buck converter with split switched inductor and cross connection of uni-direction switch results in Cross Inductor Hybrid dc-dc buck converter (CIHBDC). The capacitor electro static excitation and inductor electro-magnetic response steady state values are obtained by theoretical steady state analysis. A closed loop feedback along with QFT controller design is also applied to enhance the performance. The dynamic PSIM experimentation and MATLAB simulation results are illustrated here for performance evaluation. A 100 W, 48 V supplied converter topology which outputs controlled 12 V is designed to portray the steady state analysis. Particle Swarm Optimization (PSO), Differential Evolution (DE) and hybrid algorithm of PSO and DE called PSODE approach is applied to optimize the components of the presented converter. Further the output control voltage as fitness function is evaluated with the considered optimization algorithms.
