what will happen if i give dc 12v and 5 ampere to 2000watt inverter , how much ac ampere should it produce ?? Answered

I now what inverter does it convert dc to ac , i also know that it can convert dc 12 volt to ac 120 -110 volt but  the thing from which i m confused with is that what will happen to the ampere for example i have a 12 volt 5 ampere battery if i plugged the battery to 2000 watt inverter should it produce 2000 ac watt with just 12 volt and 5 ampere battery or i have to give more dc ampere to the inverter................ means can inverter    convert dc less volt to ac high volt  and  with also convert dc less ampere to ac high ampere   or will it convert  dc low volt to ac high volt without changing the dc low ampere and need more dc ampere or will it convert dc low volt to ac high volt with decreasing the dc ampere....

inverter on a camera flash

Ive been studying the intertubes for a bit now and I cant seem to find an explanation on how a disposable camera flash works in detail. I mean I understand that it runs with two transformers, one at 300v output to charge the cap and the other to help discharge the payload through the xenon bulb run at 2000v output. but a transformer doesn't work with out a pulse or rapid continuous change in voltage. so how is it inverting to ac or am I missing something stupid

Grid tie solar inverter power from a fixed voltage source?

Hello there! We have a 4Kw solar system installed at our home. We also happen to have 2 seperate circuits (ie 2 electricity meters). Annoyingly the solar panels are installed on the circuit that we don't use much electricity off so most of the generated electricity flows into the grid and (I know it's selfish) we don't benifit from it at all. There happens to be one lonely socket next to the solar inverter that is powered off the other electricity circuit and I'm fairly sure that the two circuits are on different phases. This is what I wanted to do and I was hoping someone might be able to validate this: I install a 240v AC to 24v DC converter (PAK650-24) and then an inverter to convert this back to 240v AC to supply that lonely socket where we need the power. Our solar inverter has a clever power detecter that switches a relay when production goes above 1Kw so I would connect this circuit to that relay. I also wanted to use a solar grid tie inverter from ebay because they seem most reasonably priced. They do however have a MPPT algorithm which is where I am not sure how it would react to a voltage source. Might anybody be able to tell me whether it would be fine to do this and most importantly about fixed voltage sources and solar grid tie inverters (which aren't really meant for fixed v sources). Many thanks, James

UPS battery backup as car inverter?

I hope this isn't a dumb question, but if I were to take an old UPS unit, remove the battery, wire a 12V lighter socket plug to the battery cables in the UPS, and plug it in to the car, would it convert the 12V DC to 120V AC while the car is running? And if it worked would it draw too much power or damage anything? I wouldn't use this to run anything with a motor, just a laptop charger and maybe a light. Thanks! :)

Current limiting high voltage - ccfl inverter help ? Answered

Okay as my first question i'll say hi first , and Darren from Ireland here , fair "know how" of electronics and how things roughly work. I have a 32inch TV who's inverter board is toast (okay its going on and off straight away) , I know its getting power from the psu board as there is little or no voltage drop when I flip the TV on and the lights fire up. I have asked 3 people at work (Electro techs at work) and they all say the same thing , replace the board , its too much work (I think there just lazy) and also they all say they would need the data sheet on all components or the circuit diagram. So well me with my stupid head wants to try and have a stab and getting a free TV. So I have ordered a CCFL inverter power source for a neon case light , which I intend to use just to see if any one bulb is gone as im not sure if that is what could be kickin the inverter off. And the other thing i have ordered is a "Universal inverter for 10-30v 4 bulb 17-24inch" from ebay. So the question is , if one bulb is gone and well i doubt i can order a bulb like this and replace as that would be end of tv if i open than panel . is there a way to simulate that bulb working in any way to stop the inverter going off because of one bulb. And the other question is , if I want to use this universal inverter , what is causing it too be a 17-24 inch only ? From what I understand is if I am wrong correct me please , that the larger bulb would burn the driver chips/fet's drawing too much current. So would there be a easy / safe way to just limit the out put so they will run but a little dim (as the tv is intended to be used in a dark room any way) Any ideas welcome , and for what ever comes up , Thanks !

Noob Q about inverter for an ornithopter

I was looking in the back of my Jameco catalog the other day and they listed a product called "Muscle wire". It's apparently a nickel-titanium alloy that shrinks as it heats up. It occurred to me that I could flap ornithopter wings with it (a really small ornithopter). I was trying to figure out how I could switch voltage from one pair of wires (the flap UP wires) to the other pair of wires (the flap DOWN wires) without a microchip. I came up with something I'm sure wouldn't work involving a couple transistors, a diode and a cap. Today on wikipedia I figured out that what I was doing was something close to an inverter.So here's the question: Anyone know of a simple switching circuit that runs on a/c power and does not have square-wave switching characteristics?I'll keep researching this myself, but sometimes 'tis quicker to ask the big-brained and kind hearted (you know who you are).

How does a capacitor charger circuit work in a disposable camera ? Can I build it from scratch ? Answered

I wanted to ask this question for a long time... In every coil gun instructable there seems to be a readily prepared circuit that changes DC into AC, steps up the voltage and then changes it back into DC to charge a bank of capacitors. My guess is that the circuit contains an inverter, transformer and rectifier... Am I right? My question is, can I build that circuit from scratch ? If yes what materials do I need ? Thank you.

Variable DC input to a clean AC out put

So here is what I am trying to accomplish. I am trying to take an old Jacobs wind turbine controller that was designed for a grid tie application and make it off grid. There is a 3 phase "wild" ac input from the turbine that is rectifyed but not clipped by the internal SCR's to variable DC (40-180 volts). The sensing was designed to tie to the grid and power sync'd to line power and freq then exported or imported depending on demand. What I would like to do is build a Variable Dc input inverter that will put out a pure sine wave 120/240 vac split phase. Thus imprinting a usable power out put and allowing the cap/choke inverter to do its part. The design need not handle much power as it is only used as an imprint to regulate the power through the controller. If anyone had any idea on a build for this or a manufacturer that is producing such an item I could really use some ideas. Thanks
