【摘要】：为便于评价Boost变换器的输出本安性能,以其非爆炸性输出本安判据及最小点燃电压曲线的数值化查询为依据,建立了基于Matlab的Boost变换器输出本安性能评价系统。采用Matlab的Simulink模块搭建待评价的Boost变换器电路,通过回调函数提取变换器的关键运行参数,求取最大输出短路火花放电能量,利用能量等效原理得到等效简单电容电路的等效电容,并与临界电容进行比较,从而评估Boost变换器的输出本安性能,还可在GUI界面中显示所提取参数及本安评价结果。采用评价系统及爆炸性试验对两组典型参数对应的Boost变换器的本安性能进行判定,结果验证了所建立评价系统的可行性。
[Abstract]:In order to evaluate the output intrinsic safety performance of Boost converter, based on its non-explosive output intrinsic safety criterion and the numerical query of minimum igniting voltage curve, a Boost converter output intrinsic safety performance evaluation system based on Matlab is established. The Simulink module of Matlab is used to construct the Boost converter circuit to be evaluated. The key operating parameters of the converter are extracted by the callback function, and the maximum output short-circuit spark discharge energy is obtained. By using the principle of energy equivalence, the equivalent capacitance of the equivalent simple capacitor circuit is obtained, and compared with the critical capacitance, the output intrinsic safety performance of the Boost converter can be evaluated. The extracted parameters and the evaluation results of the intrinsic safety can also be displayed in the GUI interface. The evaluation system and explosive test are used to determine the intrinsic safety performance of two groups of Boost converters corresponding to typical parameters. The results verify the feasibility of the proposed evaluation system.
