Greetings of the day sir! Thanks sir, it was a very infromative video. I am starting a project for AC Voltage Stablizer. I was searching for AC/AC Converters but not much literature is available on this. So I am proposing : AC/DC PFC totem pole -> DC/DC buck -> DC/DC boost -> DC/AC full bridge. I am using buck and then boost to increase the input operation range of the circuit, let us say 85Vac to 275Vac and a constant output voltage of say 230Vac. Please correct me if I am wrong and verify the schematic if possible. And please share your contact details so that I can reach out to you. Looking forward to hear from you.
Hello Vipin, you may find the following m.tech thesis relevant www.ee.iitb.ac.in/~sa/research_students.html go to "Design And Development of Single Phase Dynamic Voltage Restorer [Download Thesis]"
GaN or SiC are best because the first leg is supposed to be a high frequency leg and we need to have very less reverse recovery so these device helps us so we use GaN or SiC devices.
