电路板电源总线的分析非常复杂,虽然传统腔模方法是分析电路板电源总线的一种非常有效的方法,但是该方法具有收敛速度慢,计算时间长和不能分析电源总线辐射发射的缺点.在该算法的基础上,改进二重级数和形式的电源总线辐射发射方法并提出了单一级数和形式的电源总线辐射发射表达式.在此基础上指出了单一级数腔模理论解的适用条件,并对该快速算法的收敛性进行了分析.分析表明,该方法减少了传统二重级数求和的计算工作量,提高了收敛效率并节省了计算时间,而且能够有效逼近双级数腔模辐射算法的计算结果.通过对电路板的辐射发射数值仿真验证了该算法的有效性和正确性.
The analysis of circuit board power bus is very complicated. Although traditional cavity mode method is a very effective method to analyze circuit board power bus, this method has the shortcomings of slow convergence speed, long computation time and inability to analyze power bus radiation emission. Based on this algorithm, we improve the method of power series radiation of double series and form, and put forward the expression of single series and form of power bus radiation emission. On the basis of this algorithm, Conditions and the convergence of the fast algorithm are analyzed.The analysis shows that this method reduces the computational workload of the traditional double series of summation, improves the convergence efficiency and saves the calculation time, and can effectively approximate the double series The calculation results of the cavity mode radiation algorithm. The numerical simulation of the radiation emission of the circuit board verifies the effectiveness and correctness of the algorithm.
