Abstract: This paper presents the application of intelligent optimization techniques for optimal design and analysis of a bi-directional dc-dc converter with synchronous rectification often used in battery charge/discharge circuits in dc uninterruptible power supply systems. Converter models for simulation are designed for the forward and backup modes of operation. The results are analyzed and compared to those of the expected ideal operation to confirm the validity of the models. An objective function of the converter efficiency in the forward mode operation is derived. A constrained optimization on the objective function is performed using Genetic Algorithm (GA), Scatter Search (SS) and Simulated Annealing (SA), and therefore optimal parameters are derived. The design and analysis of the converter are performed using software tools within the MATLAB/ SIMULINK environment for GA. The analysis for SA and SS are performed using codes written in C language. The derived optimal!
parameters of the converter from GA are compared with those obtained using the SA and SS techniques.
