The Modification of Digital Current Following Control Approach of Buck DC-DC Converter

Abstract:

Current following control Buck DC-DC converter has such advantages as simple control strategy and fast response speed, in this paper, based on the existing control strategy, a detailed research is gave and a mathematical model is established to load sudden change. This improves the existing control strategy. The modified control strategies which can be divided into steady state control strategy and load change control strategy. By Simulation, the results shows that the proposed control strategy is feasible. Ensuring accuracy of output voltage while steady state, the modified control strategy obviously improves the dynamic performances, also shorter recovery time under the condition of the existing hardware parameters.
