In this study, a mathematical expression is derived to calculate the ripple value of the output voltage of 2-phase interleaved cascaded boost converter (ICBC) circuits. In this context, the total number of 432 data of ICBC circuit including four parameters (switching frequency, duty ratio, coupling coefficient and the output voltage ripple) are acquired using Ansys-Electronics software. The expression of the output voltage ripple enclosing ICBC circuit parameters related to optimization variables is developed. Afterwards, the coefficients of the expression are acquired by using an algorithm called Particle Swarm Optimization (PSO). While the mean absolute error (MAE) of 420 data is obtained as 1.5055, the MAE of 12 test data not used in the optimization process is found to be 1.4608. These results show that, the output voltage ripple of ICBC can be easily calculated closing their actual values with the proposed basic mathematical expression instead of long-term and complex simulations. In addition, the accuracy of the developed mathematical expression is verified with the co-simulation of Maxwell 3D and Twin Builder interfaces within the Ansys-Electronics software.

利用粒子群算法开发DC-DC升压变换器电路输出电压纹波表达式

在这项研究中,导出了一个数学表达式来计算2相交错级联升压转换器(ICBC)电路的输出电压的纹波值。在这种情况下,使用Ansys-Electronics软件获取了包括四个参数(开关频率,占空比,耦合系数和输出电压纹波)在内的ICBC电路的432个数据总数。建立了与优化变量有关的,包含ICBC电路参数的输出电压纹波表达式。然后,使用称为粒子群优化(PSO)的算法获取表达式的系数。虽然获得了420个数据的平均绝对误差(MAE)为1.5055,但发现未在优化过程中使用的12个测试数据的MAE为1.4608。这些结果表明,通过建议的基本数学表达式可以轻松计算出工行的输出电压纹波,以接近其实际值,而无需进行长期而复杂的仿真。此外,通过在Ansys-Electronics软件中对Maxwell 3D和Twin Builder接口的共同仿真,可以验证所开发数学表达式的准确性。
