Three phase conversion In Rush current Concern.



Original poster: "Jim Mora" <jmora@xxxxxxxxxxx>

Hello All,

Here is the schematic of my proposed three phase converter to power my
Raytheon 3 phase 24 KV DC power supply (I also have a generator in
progress). The capacitors are mid-range based on other phase converters
documentation and are subject to trail and error, to achieve balanced
output.

If anyone has experience in this arena I could use some help.

The motor will run at ~3425 rpm which has the benefit of handling sudden
change in current draw (think spark gap) and the disadvantage of inrush
current to start it up.

The motor will draw around 49 amp in static state load conditions. The LR
rating @ 240v is 290 amps, yikes. I have seen a few schematics of "soft
start" with triac's or SCR's.

I think  my neighbors to the right will see a burnout as will their
computers as we are a distance from the pig and the service wire is 1950's #
4 I think. I have upgraded to 100 amp service. Beef connected to turkey at
the Mast head.

Any suggestions would be appreciated, I am a novice in poly phase, yet know
the complexities of a seeming simple circuit.

Thanks Much,
Jim Mora
