Switching power supplies simulation software

[ElectroPhysics]

hi
does anyone know what kind of simulation software to be used for switching power supplies design. it should be free software available on the net. it may be student version although advanced version will be preferable!

Do you want a state space simulator, or a full analog simulator? You would use SPICE for the full analog simulations, but it's been a while since I looked at (the faster, but less accurate) state space simulators.

I googled state space power supply simulator, and got some good hits. Many are about SPICE simulations, and some contrast the two methods. There also are some good book hits in the list. Be sure to look at least as far as the second page or more -- there are a lot of potential resources for you:

http://www.linear.com/designtools/software/#Spice" is a free piece of software for analogue simulation of circuits. It uses the SPICE framework for its simulations and has a large library of components available.
