Abstract:
This thesis intends to uncover the concept of optimizing the operation of DC-DC converters, using closed loop control with a PI tuner, which is tuned using a unique search algorithm called Simulated Annealing Algorithm. The concept of the algorithm is to take the Kp and Ki parameters as the variables and using performance indices, objective functions are generated, which are input into the Simulated Annealing algorithm to obtain values of Kp and Ki which facilitate the global minimum of the objective function. Thereby, the Kp and Ki parameters are implemented in each individual DC-DC converter to test whether better step response is yielded than when Kp and Ki parameters are used from conventional PI tuning.
