摘要

DC-DC converters find multitude of application in the area of power electronics and associated engineering disciplines. They are used to convert unregulated DC input to a regulated one. Due to switching actions, these converters are nonlinear and have lightly damped dynamics. The DC-DC converters are generally modeled as a function of load parameters, duty cycle, and input voltage, thus making multi-variable control design difficult and challenging one. To overcome the non-linearity of the system and to obtain desired output voltage with good dynamics, the controller design plays an important role. In this paper, an overview of different controllers used for the controlling of DC-DC converters is presented such as Pole Placement, Posicast, Fuzzy Logic and Neural Network. This overview is helpful for selecting an appropriate control scheme for different DC-DC converters used in various applications.
