摘要
为选取合理的直流Buck降压变换器仿真算法,进一步提高计算结果的精度。以某DC-DC降压变换器为研究对象,建立了仿真的数学模型。分别采取ode23tb和ode15s两种算法进行系统仿真。计算结果表明,在占空比较小时,ode23tb算法的计算精度更高,而占空比较大时,两者的计算精度接近,但ode15s方法的计算速度更快。该研究的结论为后续Buck电路的数值计算,提供了参考依据。
In order to select a reasonable DC Buck converter simulation algorithm,to further improve the accuracy of the calculation results.A DC-DC buck converter is used as the research object,and the mathematical model of simulation is established.Ode23tb and odel5s are respectively adopted two algorithms for system simulation.The calculation results show that the calculation accuracy of ode23tb algorithm is higher than that of algorithm,and the accuracy of the two methods is similar,but the calculation speed of the odel5s algorithm is faster.
