一种基于混杂系统的Boost变换器切换控制算法
A Switching Control Algorithm of Boost Converter Based on Hybrid System
摘要
Abstract
Boost converter is a typical hybrid dynamic system including both discrete and continuous subsystems. Based on hybrid switching control theory, the hybrid model of Boost converter was built. And then this paper discussed the switching control strategies of the converters working in continuous current mode(CCM)and DCM modes. On condition that the switching frequency was fixed, the duty cycle was obtained by comparing the inductor current with its theoretical value, which achieved the hybrid switching control of the Boost DC-DC converter. Meanwhile, according to the principle of capacitor charge balance, the load current was estimated instead of by detection which simplified the design and im-proved the efficiency. Finally, the simulation results show that the proposed algorithms are effective.关键词
