一种移动式储能电源CLLLC谐振变换器控制策略研究
A control strategy for a CLLLC resonant converter in mobile energy storage power supply
摘要
Abstract
To address the problems of slow response and high overshoot in the existing control of CLLLC resonant converters in mobile energy storage power supply,a double closed-loop PI control strategy introducing fuzzy control was proposed.First,the topological working principle of the CLLLC resonant converters in mobile energy storage power supply was analyzed,the main internal resonant parameters were designed,and the influence of k and Q values on the gain curve was analyzed.Then the problems of the existing double-closed-loop PI control strategy were analyzed and fuzzy control was introduced,which was used to appropriately rectify the PI parameters of the voltage outer loop.Finally,the simulation model was built in MATLAB/Simulink,and the simulation verification was carried out for the input voltage mutation,load power mutation and wide range output voltage,respectively,and the two strategies of double-closed-loop PI control strategy with the introduction of fuzzy control were compared with the traditional doubleclosed-loop PI control strategy.Simulation results show that the control strategy designed in this paper can effectively reduce the steady state time and overshoot,thereby enhancing output voltage stability and achieving superior dynamic performance.关键词
