This circuit is a short running time online UPS that used high voltage capacitors to stores energy, instead of battery !
It can be used in different cases :
1-Connecting two (or more) gasoline generator together in parallel to increase the output power.
2-High voltage solar inverter without transformer
3-Online UPS with short running time
