这是自考资料！通过复习 ，好好复习。祝各位好运。(This is the Self item! Through review, good review. I wish you good luck.)

This is answer for the SSD1 certification exam.

基于平均法的buck型DC/DC建模步骤，包括电压模和峰值电流模。增加了误差放大器放大倍数的确定，电源调整率，负载调整率和三种变换器的一阶等效模型(Based on the average of the buck-type DC/DC modeling steps, including the voltage mode and peak current mode. An increase of the error amplifier to determine the magnification, adjust the rate of power supply, load-adjusted factor and three first-order equivalent converter model)

使用ANSYS求解系统在脉冲激励下的动态响应，利用APDL语言以命令流的方式实现。(system dynamic response in the pulse excitation is solved in the case of ANSYS runs the APDL language.)

ansys车辆移动荷载命令流，方便直接输入(ansys vehicle moving load command stream, convenient and direct input)
