半桥式三端口变换器建模与解耦控制
Modeling and Decoupling Control of Three-port Half-bridge Converters
摘要
Abstract
A novel control strategy with decoupling was proposed for three-port half-bridge converters (TP-HBC), achieving power management between multiple ports with decoupled close-loop control. To realize smooth and seamless mode transition, a competitive strategy was used to obtain steady-state functions under various working modes. The small signal model of TP-HBC was built by the state-space averaging method, and interactions between the control and controlled variables of the multiple control loops were analyzed in detail. Based on that, the decoupling variables were employed and the bandwidth of the multiple control loops were set far away, to decouple the multi-input multi-output control system into several single-input single-output subsystems. Thus, the decoupling control of TP-HBC is approximately achieved. Finally, experimental results verify the effectiveness and correctness of the control strategy and the decoupling method.关键词
