Hi, your unrealistic assumption | To simplify, we may assume that diode is a pure conducting device in | forward direction and pure blocking device in the reverse direction. will hinder NDSolve to work properly because the error term will infinte large when the current change the sign. A Laplace Transform may help you but that's not NDSolve Regards Jens "siliconmike" <siliconmike at yahoo.com> schrieb im Newsbeitrag news:dn0v2m$8g2$1 at smc.vnet.net... | I'm kind of curious how to set up a nonlinear differential equation and | then solve it using NDSolve in case of the following setup: | | Battery V in series with a diode, R and L. | | To simplify, we may assume that diode is a pure conducting device in | forward direction and pure blocking device in the reverse direction. | | Now how to set up a differential equation for the current I(t), that is | solvable using NDSolve? | | Thanks | Mike |
