In this paper, a simulation model of an accelerator pulse power supply with an active rectifier (voltage-type SVPWM rectifier) was set up based on the C-Model function in SIMPLORER 8.1, which is a simulation software belonging to the ANSOFT corporation. We introduce a SVPWM rectifier into an accelerator pulse power supply to solve its problems such as low input power factor, a large number of AC current harmonics and instable DC bus voltage due to the diode or thyristor rectifier used in it now. Components of control strategies developed in C language were built up and inserted into the simulation project. The simulation results indicate that an accelerator pulse power supply with a SVPWM rectifier can solve the problems above well. For all the control strategies were developed in C language, they can be transplanted into the digital signal processor (DSP) nearly without change for the prototype controlling. So it provides a basis for development of the experimental prototype.
