摘要
软开关电路系统非线性建模及动力学行为研究已逐渐成为电力电子领域研究的热点。文中从实际工程中难以设计谐振电感和谐振电容的问题出发,在分析了半桥SLR变换器的工作方式及模态的基础上,推导出了电流断续工作方式下的输出电压与电路参数的关系表达式,从而得出了谐振参数的稳定区间,并在Simulink中进行了仿真验证。所获研究结果与仿真结果一致。
Recently,the research of the non-linear modeling and dynamics in the soft-switching circuit system has become the hotspot on the power electronic field.Based on the analysis of work and model of half-bridge SLR converter,this paper deduces relational expression between output voltage and circuit parameters under the discontinuous current mode,and obtains the stability intervals of resonant parameters,then validates the correctness with simulink.The studied and simulation results are consistent.
