sorry..I read the word "charger" on that inverter case what is meant by "charger" here.Sorry but as u may no that am new and this is my first try to make an inverter by my slef so tolrate me if asked u much.
here in our country there is an inverter sold at about 200$ it is made locally the input is 12V and the output is 220V and 700 watt.can u guess the specifications of the transformer of it plz?
The 700W inverter gets warm or hot because it has some losses. The wasted heat is probably about 100W so the 12V car battery, the Mosfets and the 12V winding on the transformer must be rated for 800W/12V= 66.7A.
last question plz I am thinking of something but i dont no if it is right just thinking of it which it is that i want 2 make the circuit which converts the 6V dc into 12V dc and then connect it to the inverter since the inverter needs 12V. Will it work?if it will, can u tell me what is the specifications of the 6V battery should be(i dont no if am right or fool in such a thing)coz at the time being i cant get a battery of a car coz the cross-points are blocked and they dont allow any thing to pass these days.This is y am thinking of such a thing.and i would like to thank u much for not ignoring my question .
The 6V to 12V circuit has an output of only 0.8A at 12V. The 700W inverter needs 66.7A at 12V. Where is the missing 65.9A going to come from??
Why not make a 700W inverter with a 6VDC input and a 220VAC output? Use a huge 6V battery that can supply 133.3A. Use a 220V to 12V/134A center-tapped transformer (800W). Use many logic-level Mosfets (they turn on with a gate voltage of only 5V) to switch the 133.3A from the battery to the transformer.
Can we please keep this topic actually on topic? With over 100,000 reads it's probably the most popular and informative on this forum and I would hate to have to delete large chunks out of it to clean it up.
That said, maybe it is time to just lock it since all new questions seem to be a complete repeat of previous questions.
The Gaza strip is the Middle-East jail. Are you talking about using an inverter with a 700W load and powering it with a 100Ah car battery? The battery current will be about 67A and the battery charge will last only about an hour. The battery might boil dry before its charge runs out.
If the 700W inverter is very efficient then if it has a 100W load a 100Ah battery charge will last for 10 hours.
Where are you going to find the schematic and parts list for a 700W inverter that works?
A simple inverter uses two Mosfets or power transistors in push-pull driving a center-tapped transformer. The Mosfets have a low drive current so they can be driven from a Cmos oscillator IC that has opposite outputs. The transistors have a high drive current so they need driver transistors to boost their input current then they can be driven from a Cmos IC that has opposite outputs. The CD4047 Cmos IC is an oscillator with opposite outputs. A 555 is not.
