Current loop for phase shift dc/ac full bridge

Good morning to everybody!
I'm trying to simulate a dc/ac full bridge using Power System. The model works well, but now I would to control it by implementing a closed current loop adopting the technique of the phase shifting. Could you help me to find some example or a good reference? I would start to build the modulator using simulink blocks and after that trying to translate it in an S-function.
Thank you a lot! Vincenzo

Hello Vincenzo,
the easiest way to control phase shifting of your pwm is to create your own pwm generator using a resetable integrator with external inital condition. The input to the integrator will determine your switching frequency, and the initial condition lets you control the phase. Most of the PWM generators in the libraries do not support modifying the phase of the PWM generator durring the simulation (at least not easily).
Regards,
Joel
