Main Article Content

Wiphusana Chayinthu


This article offers the Suitable PI controller design of the parallel synchronous buck converter using the genetic algorithm. The mathematical model of the power electronics control system is proved from the generalized state-space averaging method, which is used as an objective function instead of using a physical model on a computer.  The results show that the suggested design method can allow more control efficient responses of the DC output voltage of parallel synchronous buck converter than traditional methods. In terms of the rise times, settling times, and percent overshoot, which equal to 1.01 seconds, 1.04 seconds, and 0 percent, respectively. In addition, the suggested design methods in this article can use for application to other DC-to-DC converters.
