acdc开关电源仿真

利用Cadence搭建acdc系统进行仿真，变压器不易模拟，能否为ACDC电路搭建buck系统，用以验证芯片功能。有没有利用这种方法仿真过的同仁，交流下。

    1. use veriloga model
   2. transformer model L add res

but hspice simulation long time  

跑
1~200ms 很花很花时间的
但是一会如此
..

代电感还很易不收敛拉

   I'm sorry, can you explain it more clearly, I can't catch up with you. How to use the transformer model, simply series a L and a RES to replace a winding?
How about to using a BUCK-TOP way to simulate the PSR switch ACDC IC which only test the function of IC?
Thanks very much.

    floating buck some design for LED lighting ..
Just use inductor can simulation by hspice.

If you want to simulation flyback  . need transformer model
