Pspice
I created a bunch of simulations in an older student version of Pspice which is available at
http://www.engr.uky.edu/~cathey/pspice061301.html
Below are two examples which illustrate the type of switches, diodes, and modulation techniques I tend to use. By modifying these examples, other power conversion simulations can be created.
The student version is severely restricted and the active rectifier example barely fits.
This is a standard six-transistor inverter. Change the modulation index d from 0.8 to 100 to see 180 degree VSI operation.
Rectifier - Constant d phiv.sch
Active rectifier with constant modulation index and constant phase shift angle.
