Making an inverter: A project that we have wanted to do for a long time, powering mains devices with just a battery, very impressive! We had never succeeded (by using a logic and not by taking a version created by a third person, that's where the interest lies, to use the logic of electronics to manufacture complex devices as easily as possible ).
The key to operation and unfortunately the most difficult "part" to find via recovery is the use of a transformer with two secondaries (or two primaries depending on the direction in which it is used) which are both of the same ratio (1 for 1) and in the opposite direction (if we put an equal alternating current in each of them it would be canceled...). We can therefore alternately put positive currents of the "cos²x" and "-cos²x" type, which are easy to create with an oscillator, in the primaries so that the secondary coil increases their voltage and transforms them into a sinusoidal current... (greater than 0 when it comes from a "cos²x" and less than 0 when it comes from a "-cos²x"
In this video we present you a rather finished version of our inverter to test it on different devices, and it works really well! unlike the Dynamo 230 Volts which was our first attempt at an inverter, this project is compatible with all devices consuming 30 Watts or less, is that actually not bad, incandescent bulbs, several energy-saving bulbs at a time, stereo fi! Laptop (live powered), all transformers...
For once we have oriented the video on a very explicit second part where we are not content to give you our diagram but where we explain to you how our inverter works step by step to help you manufacture it, understand the operation of a oscillator (to make it go to one of our old videos), the roles of transistors and their logical operation then the transformer. The biggest difficulty will be to get the components^^ a word of advice, the older the devices, the better they are "equipped" with useful components for us (cathode ray tubes, video recorders...)
