中文说明：DC-DC部分采用定功率单环控制，插值与拟合，解方程，数据分析，进行逐步线性回归，解耦，恢复原信号，用于信号特征提取、信号消噪，一个很有用的程序。
English Description：
DC-DC converter using power single-loop control, interpolation and fitting, solving equations, data analysis, stepwise linear regression, decoupling of signal recovery, used for signal feature extraction and denoising, a very useful program.
