基于电容电荷平衡的Boost型变换器控制研究
Research of Control Strategy Based on Capacitor Charge Balance for the Boost Converter
摘要
Abstract
In view of the limitation on the performance of the Boost converter when the general controller is used, such as low-bandwidth and sluggish dynamic response. This paper proposes a novel nonlinear control scheme which is based on the capacitor charge balance control (CBC). Combined with the linear/nonlinear control method, the traditional voltage mode control is taken during the steady-state of the Boost converter, the scheme switches to the nonlinear control method while the load current has a step change. Using the CBC algorithm during the calculation of the switching time, the optimal dynamic performance of the Boost converter is achieved. Finally, the simulation results and the experimental results of the prototype show that the proposed algorithm, compared with the traditional voltage mode control, can significantly improve the dynamic performance of the Boost converter, such as the overshoot, dynamic setting time.关键词
