My "perky\cat/volvo" DC bat charger

[Lloyd]

These are an interesting off the shelf solution..that can apply to many of our co-gen apps...especially if it's on-board a vessel or vehicle.

DESIGNING A BATTERY CHARGER
Vicor's BatMod (current source module) enables designers
to easily build a compact, lightweight battery charging
system with commonly available parts. The BatMod
provides programmable output current and output voltage
capability. Since the BatMod allows the output voltage
and the charge current to be set independently, the
system design is greatly simplified.
Basic Battery Charger. Figure 11–3, shows a basic
charging circuit with a BatMod for the following
system requirements:
Battery voltage: 12 V
Float voltage: 13.8 V
Charge current: Adjustable 0 – 14.5 A

I am waiting on Osbourn transformer to finish my trans/rec...In searching for future silicon solution, I found this off the shelf for a 3 phase toroidal 6 pulse buck rectifier.

http://www.globalspec.com/FeaturedProducts/Detail/Powertronix/3Phase_AC_to_DC_Power_Supplies/6670/0


I emailed my specs to them..and will await a price quote...I am committed to Osbourn, for the first trans/rec...but though some may interested in this link.

I'll let everyone know the final price quotes from both.

Lloyd

[mobile_bob]

the one that is pictured and linked to does not look like it is a buck rectifier, but rather a straight up
transformer rectifier??

do they make a buck converter type?

bob g

[Lloyd]

Hi Bob,

Yes, they do make a buck, or buck/boost...I spoke with them today. He said all I need do is send them my specks and they will put it together...

Here's Powertronix http://www.powertronix.com/manufacturing.phpweb site re; design...I meant to put this link and not global spec.com

I also spoke with Viscor today, they referred me to their design engineer...they will make a plugNplay black box, no transformers all silicon buck, buck/boost...and he also said if I need they could add a frequency converter, so that it would be capable of providing 120 6Ohz, in addition to the bat charger...he suggested that it would be no problem, and would be advantages after the the bats hit absorption...then It would auto-transfer to  120 60 hz, while maitaining enough to continue into absorption/float.

that would sure give me some options.

Lloyd

Lloyd:

sounds pretty interesting to me, and i look forward to what you find out

keep us posted

bob g

[Lloyd]

Hey Bob,

This is a link ti Viscor product...their Brick design it's modular..and has some real options, http://www.vicr.com/cms/home/products/brick/MegaPAC

They have a network of contract designers that are familiar with all their product lines. That is whom they referred me, the designer will spec the black box and Viscor will build it from their components.

I am really interested in this option.

Here's the Vicor Bat Mod in action...whats really funny is "highwater"]http://www.microcogen.info/index.php?action=profile;u=409]"highwater" found the fithwheel and posted it to Bolt on Electric Hybred Conversion to your existing Automobile]http://www.microcogen.info/index.php?topic=916.msg11250#msg11250]Bolt on Electric Hybred Conversion to your existing Automobile

A fifth wheel.

I read the article here http://99mpg.com/Projectcars/mikesinsight and the guy is using the same Bat Mod brick for his hybred charger.

Filling my electric tank with zero carbon produced electrons
To plug into a coal burning utility grid, sort of reduces the advantages to having a booster battery. I had some solar panels and decided to use them for keeping my batteries charged. I wanted to make simple easy to construct mount for the panels that would be in close proximity to the car in the garage.
I made stainless steel mounting brackets and attached them to each of the 8-50W panels both top and bottom. I screwed the top brackets right into the T-111 siding, and the bottoms to a fir strip 2" X 1.5 ". The angle was set with two wooden standoffs. The DC from the panels is 75V @ ~6A. The solar charge controller is a simple op amp servo circuit set up to turn off the charge when the voltage on the pack gets to a set voltage. The AC charger is a Vicor DC/DC batmod, powered from rectified and filtered AC. A simple flip of a switch switches from one to another.
First EV range test.
23 miles 45% charge remaining, average speed 28 MPH.
It works yea!

Something about 6degres separation I think

This guy..seems a real DIY...somethings  he makes to simple ...but if it works..it could provide at least a working knowledge of the clawpole

he does pretty well with his understanding of the function, however
in my opinion he underestimates the reduction in field flux that is being shunted by the steel shaft.

many folks have done what he is describing, and done so before he posted this site, and have
quantified the loss associated with the steel shaft.

their interesting fix was to replace the steel shaft with a stainless steel shaft, this takes away a significant
pathway for the neo magnets flux and forces it to all go up the end bells and into the clawpoles.

otherwise in theory his machine will work, but then again he has to some degree underestimated what the
power derate will be with the modification of the stator windings, he has added significant amount of resistance
and cuts its current capability in half.

not necessarily a bad trade off for a unit that will make some power in a wind gen application, and if you can
get a hold of a suitable magnet probably a better solution than one of the many overpriced and underperforming
pm modified gm alternators offered all over the place. even some of those that are offered understand the need
for a stainless shaft and have made that change.

I just finished speaking with the Vicor design lab, and this is there proposal. They said that my alternator will run cooler bc of the design load balance, and PFC.

I will need to control the field of the Alt separate of their unit, so I will add a potted voltage switch.
