Hi,

i need a simple circuit for a Single phase to three phase inverter
also 50Watt .
Somebody knows where find a simple circuit?
Thanks

If your load is fairly constant, you can use passive components to
make a 'fooler box'.

Small single-phase to 3-phase inverters are readily available and
inexpensive on ebay.

They are called VFD's and are a low cost commodity item.
There is no possible way you could build one for the selling prive.

A Scott-T transformer can convert 2-phase to three phase, not single
phase to 3-phase, and no, the line voltage in US/Canada homes is not
two phase, it's single phase with a centertap.

There are a few approaches:

- static phase converter
- rotary phase converter
- synthesize the three phases with electronics (inverter)

As Don L. says the three phase inverters are low-cost commodity items
(okay, also extremely costly military and aerospace items!) and you
can purchase them off-the-shelf, in high and low power and high and
low voltage versions.
