A new “model-free” control methodology is applied for the first time to power converters, and in particular to a buck converter, and to a Ćuk converter. We evaluate its performances regarding load and supply variations. Our approach, which utilizes “intelligent” PI controllers, does not require any converter identification while ensuring the stability and the robustness of the control synthesis....
DC-DC Converters widely used in regulated switch mode power supplies and in dc motor drive applications. Often the input to these converters is an unregulated dc voltage and therefore it will fluctuate due to changes in Line-Voltage magnitude. In this paper the PID controller has been used to overcome this problem. The controller parameters are optimized by using the Bacterial Foraging Algorithm (BFA)...
This paper presents the small signal model and closed loop control design using average current control for an L-L type active-clamped zero-voltage switching (ZVS) current-fed isolated DC-DC converter. State-space averaging technique is used to derive the small signal model. The controller is designed for fixed-frequency duty cycle modulation and works for wide input voltage and load variation. A...
In this paper, two different control methods on DC-DC converter, are compared with together. These converters, are used for the stabilization or the control of DC voltage of a battery. In addition to other applications, DC converters feed electric vehicles (trucks, electric vehicles, and subway locomotives), telephone sets and civil inverters. Lately, improvement the performance of the DC-DC converter,...
