Hello,
I need to design a charger for a 400V-82mF capacitor bank from 50Hz ,220V mains. Charging time must be less than 30 seconds. There is no extra load other than capacitors. After charging, capacitors discharges to xenon lamps when triggered, then charging again.
I don't know which topology best fits with this kind of application. A full wave rectifier with doubler would be ok but the power factor is very low (~0.3).
Regards,
Mehmet.
