capacitor - transfer function of a full bridge diode rectifier


I'd like to find the s-domain transfer function of a full bridge diode rectifier with capacitive output filter. Surprisingly, there doesn't seem to be much literature on this.


Analytically, I am unsure how one would approach this problem, but I imagine the simplest method would be to use simulation to get the frequency response.


So, I tried to do this using PSIM software, but did not get very good results. I'm not actually sure what to expect from the magnitude plot, but I do think there will be a 90 degree phase shift from the capacitor.


Is anybody here aware of some analysis regarding this? Or if someone has a working simulation? Here is my schematic, but I'm not quite sure where I have gone wrong.

thanks

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
