Online UPS with Capacitors

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
