I have recently started to venture into electronics as a new hobby (which will also compliment my other hobbies too) and find these videos to be rather enjoyable to watch . Keep up the great work my friend, many thanks 😀
can you please explain the circuit in detail, i would never be able to die in peace if i don't understand this,it is complex and i cannot understand it on my on, i want to understand the flow of current and switching on and off of transistor gates, thank you
Transformers need oscilation to work, and the battery will provide DC So, you use two mosfets to oscillate between positive and negative phases (AC) with that middle wire working for feedback.
There is an error in the schematic at the end. When you built the circuit, R1 and R2 are connected across the gate and source of each transistor. The schematic at the end shows R1 and R2 connected across the source and drain of each transistor. The way the circuit was actually built is correct.
@@shenk9510 I tried it myself, and it works perfectly. It does put out a square wave, and with the transformer I used, it runs at ~40 Hz unloaded, when loaded to 40 watts, it runs at ~50 Hz. Because it relies on transformer core saturation to turn over the "flip flop", it does have a high idle current. The MOSFETs don't get hot, but the transformer does warm up slightly. Mine idles at about 15 watts. Bottom line....The way it's built in this video IS correct! The schematic is incorrect. If you need a cheap, cheesy step up AC inverter to charge a cell phone, run and incandescent, LED or compact fluorescent light, this circuit works perfectly as shown.
@@eng.mohamedsaad9541 The way he built it, with two resistors across the gates and sources of the MOSFETs, and the other two connected between the drain of one, and the gate of the other, indeed works. Watch the build, ignore the schematic. The frequency varies with load, and it puts out a soft square wave. If you need a cheap, cheesy inverter to run incandescent, compact fluorescent or LED lights, this works as well as shown. Mine runs at ~40 Hz unloaded, and ~50 Hz loaded. It does have a high idle current, (about 1 amp), but the transistors don't heat up, even when loaded to 40 watts. The transformer warms slightly.
I don't recommend IRFZ44. the maximum gate-source voltage voltage on that device is only 10 volts. It is a logic level mosfet. The mosfets used in this video are standard threshold devices, allowing up to 20 volts across the gate-source. This circuit uses a ~12 volt supply, which can easily exceed the 10 volts allowed by the IRFZ44. Even though this circuit has a voltage divider on the gates created by the 1KΩ resistors, when you use a center tapped transformer, when one leg is pulled to ground by one transistor, the other tap goes up to double the supply voltage, meaning the gates go up to supply voltage. One thing you might try, is reducing the resistors connected across the gates and sources of the transistors to 470Ω. That will reduce the gate voltage to~7.67 volts, more than enough to turn them on, but well within their safety margin.
Buenas tardes. MI pregunta es: Supongamos que yo conecte un electrodoméstico a la energía generada de 220V, que consumo se reflejaría en la factura de mi servicio de energía; como si el consumo fuera del electrodoméstico usando 220V, o se refleja la energía consumida en el proceso de carga al inversor en caso de usar un cargador de 12V conectado a la red de energía eléctrica?
You can not create energy. If voltage is up then amper is down. Opposite is true also. So if you use a device 220v 200w then it uses 200w in 12 or 24v too. So you pay the same. If losses in the conversing circuit are added you may pay more
Hola campeón .estoy buscando algo que me dé 18 volt con 1 amper ....y no hay problema si me.da más volt o amperes ... Es para un electro imán ..un invento .... E visto videos que dicen que aumenta potencia hasta 220 incluso 700 volt pero el amperaje es mínimo de unos 20 Mili amperes ...... La pregunta vos lo probastes en un amplificador ..cuántos amperes usa tu artículo???? electrónico ?????
You don't need a fancy inverter like this. Connect each 3 LED's in a series, with a 220 Ohm resistor on each series of 3. Just connect that directly to the battery. It will put ~20 mA through each LED. Adjust the resistor values, to get the current you need. (I'm assuming, you're running white LEDs)
gumawa ako nito sir paulit ulit kong tiningnan lalo ang pagkalagay sa pyesa nung ikabit ko na ang batter walang ilaw lumalabas pag bunotin ko alin man positve or negave s terminal ng battery may flash ng ilaw pero nawawala din.no kaya ang deperensya Sir?
Hola buen.tarde amigo una pregunta esto video necesita 110 v bombillo 60w o 100 w aqui venezuela se lleva la luz apagado cuando llega la luz como 5 hora llega la luz situacion
Si se ouede. Solo hay que cambiar el transformador por uno de 12 v 110v. Lo demas igual. Puede conectar hasta 4 bombillos led de 110v 9w. Son eficientes.
It can run anything that needs 230V but he showed up it on example (light) you cyn use it on Electronic motor but take my words: Battery will discharge fast if you dont have alcalic 9V battery
Tenkyou türkish Ali tavana asılan LED aydınlatma bu lamba içerisinde 4 adet 120 cm boyunda LED şerit var bunların giriş besleme devresi şema sı rica edebilirmiyim
The method shown in this video does not work for a specific frequency. The frequency you would get is based on the capacitance of the mosfets. You would need a microcontroller with pwm and MOSFET drivers to get an accurate frequency
I have a question anyone please answer. Does the 220V electrity given of by the power inverter cause electric shock to humans when accidentally or technically purposely touched ಠ‿ಠ or does it not? Thanks.
I know that but my point was for everyone who watches my videos they prefer non breadboard circuits and also it is easy to understand. So, I make circuits like that. I will keep in mind your choice. Cheers!
It will work fine. Build the circuit exactly as shown, it's correct. The schematic has an error. For 60 watts, it's best to mount the MOSFETs on a small heat sink, make sure the transformer is big enough. (A 60 watt bulb will pull about 5-1/2 amps out of your 12 volt battery)
Je ne pas l'intérêt de faire ce montage il vaut mieux brancher les ampoules directement sur le 220 volts aussi c'est des ampoules baïonnettes 🤯 il les a acheté en France ??? 👍🇫🇷🇪🇸🇧🇷
