Dc to AC is an Inverter.

If it does not have a big transformer in it is an inverter.
Inverters turn whatever you feed them into a high frequency square
wave (20kz or more) them get the voltage they want with a tiny little
transformer.
That can be up or down.


Switching power supply.

Problem is, some converters are now based on switching power supplies.
Most of the small, inexpensive, 3 stage battery chargers/maintainers use
them.




I'm having trouble distinguishing between converter and battery
charger.

===

The two are sometimes interchangeably but that's not really correct. A
true converter is designed to provide a steady DC voltage at a level
that approximates a fully charged battery, about 12.6 to 13.2 volts.
In effect, a converter is a DC power supply.

A charger on the other hand, must supply a higher voltage initially,
typically in the range of 14.2 to 14.6 volts, and then taper off as
the battery becomes fully charged.

Depending on the mode, my converter puts out three voltages:

Absorption Mode: Normal operation. Output in 13.6 vdc range.

Bulk Mode: Output switches to 14.4 vdc for max of four hours. Could be a short in battery cell or
other issue.

Float Mode: Battery charging only with trickle charge of 13.2 vdc. When a demand is placed on
converter, like turning on lights, operating slides, etc, the converter switches automatically to
Absorption Mode.


That's typical of the newer converters and battery chargers. Looking at
the picture you posted of your new one I suspect it's also a switching
power supply device. Too small to be of the older types.

I forgot also to include a reply to Greg's question about if the truck
charges the house battery in a RV. It does because the house battery
is also used to power the trailer's electric brakes. In the event of
a "break-away" the small cable that you hook up in addition to the
safety chains causes the trailer brakes to be applied, powered only by
the trailer's house battery.

I'm having trouble distinguishing between converter and battery
charger.



For RV purposes, I think of it this way:

If you are at a campsite or whatever and connected to shore power
the converter is charging your house battery but is also supplying
12vdc to all your lights and other 12vdc devices. I suppose you
could say they are really all running off the house battery and
the converter is simultaneously charging it. But, you could remove
the house battery and the lights will still work.

Does the truck charge the house battery when it is running? If not,
why not?


Yes, I think it does.. . Come to think of it I am sure it does.
Even on the little travel trailer I just gave to my daughter and husband
the "house" battery on the trailer was being charged when my truck was
running. One of the pins on the 7 pin trailer plug on the truck
supplies the charging voltage.

I had a class C RV ... the previously mentioned Chinook Glacier. It had
two batteries ... one was the "engine" battery and the other being the
"house" battery. It had a sensing circuit that directed the alternator
charging output to the battery that had the lowest voltage whenever the
rig was running.

I suspect something like that is also used in diesel pickups that have
two batteries.

To expand on that, I used to have an older Winnebago class A that worked differently. The chassis battery was by default used and charged by the motor, and the house battery only charged by shore power or when the gen was running. There was, however, a pair of switches up on the dash that let you connect the house battery to the chassis for charging while running, and for emergency cranking. No automatic sensing on it.

On one trip we were running in the rain on the Penn Turnpike. I noticed the lights getting dimmer and the wiper running slower, and realized I had a problem. The alternator had died. I pulled over and fired up the generator, plugged in a battery charger I had brought along and hooked that up to the chassis battery without ever shutting down. That got me to the next exit that had a repair shop. They were busy but agreed to get me parts and let me use their parking lot for doing the repair. I swapped out the alternator and we were back on the road.

The way you described it, with multiple voltage modes, it would more
properly be called a converter/charger since it can fill both roles.

Unless your device can convert 12 volt DC to 120 volt AC, and I don't
think it does, it is definitely not an inverter or inverter/charger.

Inverter/chargers are much heavier and more expensive. I've got two
on the boat (one for backup), and one at home that I use as a heavy
duty UPS for my computer equipment.

So the site is wrong? Mine does not have a big transformer as it is not
expected to transform 120v
to 240v or vice-versa. The item I just installed is a converter. It
converts 12vdc to 120vac.

Your converter is pretty much like the "power supply" in your PC. In
fact a PC power supply can give you 12v at 20a or more if you have a
big one. (I use one for a bench supply)

Watch the video.

https://www.arrow.com/en/research-an...vs-transformer

Converters also have only job: convert AC power to DC power. But the
word “converter� is very
generic, and you may often see it being used incorrectly. For example,
if someone says “DC to AC
converter,� that makes logical sense even though the correct terminology
is “DC to AC inverter.� The
same argument can be made by saying “DC to DC converters.� AC to DC
converters are also regularly
referred to as power supplies.

Inverters ultimately have only one job – take in DC current and turn it
into AC current. In theory,
this is very easy, because a simple switch and some creative wiring can
give you an alternating
square wave operating at the frequency that you flip the switch.

But in reality, square waves are very damaging to nearly all modern
electronics that rely on AC
power. So the real question is: How do you take AC power and turn it
into something useable? The
answer is, you can filter the square wave using precisely selected
inductors and capacitors to
create a sine wave, or at least something close to a sine wave.

Oftentimes, inverters will also feature a transformer. This is done so
that the AC voltage out can
actually be different from the DC voltage in, depending on the number of
coils on the primary and
secondary winding.

Maybe that will help clear it up.



There is also a lot of arguing about nomenclature (converter,
inverter, power supply etc) and I have no opinion. "Inverter" does
imply an A/C output tho whether it is pure sine wave, modified sine
wave or just a square wave. The rest of them seem to be the same
thing.

I disagree with one thing in particular. "Modern electronics" don't
really "use" AC at all. (for the last decade or two) If it has a
switching power supply the first thing that happens is the input is
changed to DC at 1.4x the nominal line voltage (the peak to peak) and
then it is chopped to a high frequency. (I bet they would work as well
on 100-250vdc) This chopped DC is changed to the desired voltage with
a small transformer. The input can be the noisiest, most unstable
thing you throw at it and the supply cleans it right up. The noise
filter on your PC, TV or whatever is to keep the noise IN, not out.


At System Industries, one of our biggest problems on the controllers was
the Pass
Transistor power supplies passing any input line glitch through.
Especially bad in the Rockies as they had lots of terrible lighting storms
and little damping on the power lines. I tried to go to,a,much cheaper,
much better switcher, and was told by the Veep on manufacturing he had
ordered a thousand of the old supplies. Who the original manufacturer was
telling they were dropping. 4x TS price of the switchers.

Yes it does. When travelling 12 volts is still needed.

So in a jam you could plug the truck in and charge the house battery
enough to get the jacks working and such.

As I said it works for me but then the wall wart that charges your

Back when they were fairly new (early 60s) IBM called those supplies
"inverter/converters" covering all bases I suppose.

As John said, semantics. The "Inverter/Converters" I grew up with put
out one DC voltage, from 208/230 VAC in.
The "inverter" referred to them stepping the frequency up to 20,000 hz
before it went to the step down transformer.

Inverters turn whatever you feed them into a high frequency square
wave (20kz or more) them get the voltage they want with a tiny little
transformer.
That can be up or down.


Switching power supply.

Problem is, some converters are now based on switching power supplies.
Most of the small, inexpensive, 3 stage battery chargers/maintainers use
them.




I'm having trouble distinguishing between converter and battery
charger.



For RV purposes, I think of it this way:

If you are at a campsite or whatever and connected to shore power
the converter is charging your house battery but is also supplying
12vdc to all your lights and other 12vdc devices. I suppose you
could say they are really all running off the house battery and
the converter is simultaneously charging it. But, you could remove
the house battery and the lights will still work.

Does the truck charge the house battery when it is running? If not,
why not?

Yes it does. When travelling 12 volts is still needed.

So in a jam you could plug the truck in and charge the house battery
enough to get the jacks working and such.



Yup. I know when I first bought the little camper that I gave away the
battery was on it's last legs. The monitor inside the camper would
display that it was almost fully discharged. Hook it up to tow
somewhere with the truck and when I arrived the batter monitor indicated
"full" but would rapidly discharge because it needed to be replaced.

Good to see you understood his whine. I'm still not sure what he means
by 'same bluegrass festival
on different sites'. Maybe because the music is similar at each festival?

It gets to where the music takes second place to seeing and having fun
with good friends.

.......

At least you?re getting fresh air, exercise, and sunshine.
Btw, I rode my Guzzi 400 mi this week...so far. Might get another 200
mi in before Monday.

I think I'll take mine for a ride tomorrow. I finished installing the new
converter, and now I'm
tired. Climbing in and out of that thing is a bitch.


Dc to AC is an Inverter.

Agreed. My converter converts 120vac to 12vdc.


The one I replaced in my Palomino camper did that also was called an
inverter.

Maybe they were just calling it the wrong name.

Depends if you hook up to the truck charge line. If you do, you need a
charge relay, so you do not run down the truck battery when parked. Also
need a disconnect for the charge relay if in the truck. Draws about 15 ma
in off position. After a couple weeks truck battery is dead. Been
there.
