I created a bunch of simulations in an older student version of Pspice which is available at

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.
