Simtrix.simplis仿真基础.pdf

Simetrix/Simplis 仿真基础 近 4 年开发电源的过程, 在使用仿真软件的过程中, 对仿真 渐渐 有了个了解,仿真不能代替 实验。仿真软件显示电路不能工作,而实际确能工作,仿真不收敛,而实际电路永远不会不 收敛。 但是仿真软件可以 测试 未知电路,可以验证自己的想法, 甚至大大缩短开发过程, 在 你仿真的过程中, 也 可以更深入的理解开关电源的拓扑结构,控制模式等,假如你要实验一 个电路,发现库里没有现成的 IC, 在自己搭建 IC 之后 ,你对整个 IC 具体是如何运作的 必定 了解的非常清楚。Simetrix/Simplis
