It isn't that difficult. Take three identical single phase inverters and
synchronise them to a simple phase shift circuit. Connect their internal
(analogue) oscillators to pull them into synch with the correct phase
This is normally easy to do, except that models with a crystal
controlled, divider chain, 50/60Hz reference need a different approach.
You need to disconnect two of the clock generators and use the third as
reference to all three - with simple counters to inhibit the output to
two channels for the required number of clocks that equate to the
Or use a standard single phase UPS and connect it to a three phase
converter, such as Ebay item 8035464334.
There are plenty of circuits of single phase inverters and plenty for
three phase converters.
A UPS is not a lot more than a charger, an inverter, battery and a bit
of circuitry pulling it together. You will probably be better off by
starting by looking at the design of the individual elements.
If you want a circuit for a typical phase shift circuit, just ask..
Funny. I like your sense of humor when confronted with an idiotic
By the way, I am interested in making my own hybrid car. Can anyone
please send me the schenmatics and make suggestions for doing so?
