I believe the discussion was braking performance and your specific lack
of data on that issue--a lack of data which did not prevent you from
declaring that "braking distance was OK because I let the ABS kick in".

You are SUCH a tool...

"Electric AC Compressor in Dixie" is the thread title. Regardless,
I'll start a fresh thread once I get some technical details from the
vendor on their 1.5kW inverter.

put together some random words that came up with:

I would sorta doubt that DC-DC inverter would sustain a 125A continuous =
unless there was some way to dissapate the heat.  Some experimentation =
might be in order.  Cranking up the current load until 125A is reached.

Have you ever looked into the idea of running an inverter off the =
battery?  If so, what sort of current could the MG supply?

The DC-DC converter (not inverter) is part of the main inverter and is
liquid cooled.

He doesn't have to, that is what http://www.priups.com  is for

No! No!  I mean Traction Battery (180v/375 Volts) -> 120V/240V 60Hz (an

It would be a nice Sr. project for a talented EE student.  A conventional=
phase boost switching converter into a 480v 3 Phase-> single phase =
(kinda like they have on power poles, but smaller).

You can get them here:

I don't know how high the traction battery gets, but for a simple =
inverter, a
single phase boost converter to 277V to a stepdown 120V/240 transformer =
do the trick.

With the 3 phase, you need smaller thyristors.

You have to get to 60 Hz anyway, so why not do it in one step instead of =
3? Much
more efficient.
