BDF离散伴随网络法在电力电子电路计算机仿真中的应用

Application of BDF Discrete Adjoint Model to Power Electronic Circuit Computer in Simulation

本文结合电力电子电路的特点,系统介绍了二阶变步长后向差分法(BDF)离散伴随网络及变步长的方法。该方法稳定性好,变步长容易,运算工作量小,最后给出了具体的电力电子电路计算机仿真分析程序图,并把实验及仿真的结果进行了对照,证明程序及方法的正确性和有效性。

This paper will systematieally deal with 2-order varying-step BDF diserete adjoint model in the light of electrical circuit characteristics and the method to power cleetronic circuit which leads to bctter stability, casy varying step, less operation. Finally, the probtem analysis diagram (PAD) of CAA is set up. Comparing the cxperimental result with simulation proves that the program and the method are both correet and effective.
