Abstract

In this paper, Buck converter circuit that is a power electronics circuit topology is handled. The dynamic
behavior of the DC voltage level which is the output magnitude of the circuit has been optimally
controlled. The discrete time PI algorithm is chosen as the controller. In order to keep the control process
cost low level, Kp and Ki which are controller parameters were optimized. Firefly algorithm (FA), which
is an iterative algorithm for optimization, has been run for the purpose. Concurrent studies of the control
process have been realized on Matlab-Simulink platform and the results were argued
