چکیده
An approach to the analysis of large-signal stability of a Boost converter via the small-signal loop gains is presented. The large-signal stable region of the small-signal designed bilinear Boost converter is estimated in light of the Input-output stability concept. By doing so, the effects of small-signals on large-signal stability are revealed. The effectiveness of the presented approach is verified by simulations and good agreement is reported. Streszczenie.

In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
