Hi All,

    During last week I had to made some rather complicated simulations of 3
phase AC/DC converter. I wanted to use simple SCR model made of switch and B
control source. As build-in spice switches change their states instantaneous
they are not very useful for transient.

I looked and switch code and it seems that it will be easy (:-)) to improve
it. My idea is to make the switch that will change its state exponentially in
transient and DC analysis, and behave like normal ON-OFF device for the rest.

Is it correct? Please send my comments about what do You think about such
change in the code.

Michael
