摘要
基于耦合电感的高增益变换器在新能源发电和直流微电网中均有良好的应用前景。论文在分析基于耦合电感的高增益升降压(Buck-Boost)变换器工作原理的基础上,采用开关流图法建立变换器的模型,详细推导了变换器的稳态模型和交流小信号模型;电力仿真(PSIM)软件对变换器小信号模型的仿真结果证明论文模型的正确性。论文结果对高增益DC/DC变换器控制回路的设计具有较高的参考价值。
The high gain converter based on coupled inductance has a good application prospect in both new energy generation and DC microgrid.The operating principle of high gain Buck-Boost converter based on coupled inductance is analyzed,the switching flow diagram method is adopted to establish the converter model,and the steady state model and AC small signal model are derived in detail.The simulation results of Power SIMulation(PSIM)software on the converter small signal model prove the correctness of the proposed model.The results of this paper have high reference value for the design of control circuit of high gain DC/DC converter.
