Is there any criteria to make the DC voltage choice in the presence of many supply voltage in the electronic cart? For example: supply voltage: 12v ; 5V ; 3.3V ; 1.1V ; 1V For the AC voltage : 220v So what supply voltage should I choose for the first conversion? 220v/ (...)
Hello I would like to design a power supply for a wireless transmiter (4W max output power with Vin=12v). I don´t know much about power supplies and I would like to design a reliable and more or less small one. I would appreciate any sch. or link. thanks a lot anyway, mimoto
froggy so You want convert twice from 12v to 24V and next 24V to 220v hmm I don't think it's a good idea.. 12v DC need to change 12v AC, next to 24V AC by 1:2 transformer (very large) next use bridge, caps to get DC and convert to 220v... no this is very wrong idea.... here is an example simple (...)
Hi, How to get the +5V (30mA) and +12v (20mA) directly from the main 220v (AC)? I need a simple circuit, not to much loses, and avoid of using transformer. Anyone have an idea & willing to share? Thx + Rgds, TR2000
I need to do a 220v-12v 50hz transformer, and it must decouple the ckt from the source line, but I must to use pie winding design to improve the insulation. Ok my question is, how can I do to implement the Electromagnetic and electrostatic shielding in a pie winding transformer?. I did it in a concentric winding transformer, introducing a c
anyone please help on creating POWER INVERTER from 12v to 220v..output would be a pseudo sine wave not square wave.ü

Hi I need schematic for 12/220v 300W converter.
Now, I have a 220v/12v transformer. I wan to build with it a 0..30V power supply. Do you have any idea? Or I just build a 0..15 V power supply?
This inverter is maded with IRFP150 mosfet transistors.
Hi myouss, I am sure it certainly possible to build a sine wave (100KHz - 500KHz)generator using 12v DC. For a less load it is even simpler.I am describe the method for lesser load. Build a 12v 100KHz sine oscillator and connect the output to a step transformer. for example 9V to 220v step up transformer. For 100KHz transformer has to (...)
hi all.i want a circuit that convert 220v AC to 12v DC without using transformer.i want it give me not less than 40 or 50 mA.and also it costs so cheap.its better not using an ic. thanx very much
hi all plz tell me or give any circuit which can drive normal 40W 220v AC tubelight by 12v DC
Hello i need schematic on transformerless PSU with this spec : - AC IN 220v - DC OUT 12v or adjustable using regulator ic - dc current minimum of 500mA thanx
Need help with DC/AC inverter from: Cant find replacment or datasheet for UD1208, and there is no info on the schematic about transformer T1 and T2 ( U prim., U sec. and P)
I don't agree either with the LED solution neither with the series solution. Things are quite simple: Check the Wattage of the bulbs ( POWER disipation in each one of them). If it is say 10Watts each, then do as following: SAY you have a 220v as main supply. Then Connecting all the bulbs in parallel will cost you : 30x10=300Watts. therefore
Dear sirs I need a simple and low power (5w-10w) 12v to 220v inverter circuit. thanks alot and best regards.
i am looking for a 220v dc to 12v ac inverter
From what you ask it sound like you need a 220volt inverter This will give you a 220volt 50hz supply and these can be bought very cheaply now as it is the sort of thing people use to go camping and run tvs and radios etc fro a mains supply.
Could you try and explain what you mean. An inverter won't convert 12v to 220v. Try a step up transformer if it is ac. Edit: Sorry, I'd never heard of this type of inverter!
Hi Can anyone tell me wich chip should I use for isolated 220v to 12v switching power supply. (20-40w autput power)
(updated) HELP! Input: 30 - 130 AC peak to peak voltage (50Hz) Output: 220 AC(p-p Voltage) The frequency of output have to be around 50Hz. I have no idea to use what PWM controller for the inverter circuit It is the inverter circuit i found on internet: simple & easy is ok, so
would someone be kind enough to guide me a way to calculate hysteresis losses and eddy currents in a 220v input and 12volt output transformer. thanking in antcipation to all good friends

Hi, pls could anyone help me with schematic? I'd like to modify the schematic below to use 12vdc output from bridge? Is it sufficient to change only the value of Zener diode to 12v? What is a proper value for C1 for my case? ? And shouldn't

I want to make a 12v to 220 v inverter via a computer backup .I just plug the 12v of my car instead of its battery .logically it will convert the 12v into 220v.Does this work .If no, why? thank you all
HI GUYS... Can somebody help me in this project? please give me a schematic of 12v to 220v inverter w/ lead acid battery charger... thank you in advance...
Yes, you can charge with the same transformer, but not 8v. What you need is a primary voltage control, either variable or fixed. This is usually done using a triac or 2 SCRs and another tapping in the transformer (I used 140v). The control of the triac/SCRs is done using phase angle control with either opamps (a complicated circuit) or if you can u
I need help on a Inverter as this is my first time I have A 12v DC 3000W Inverter 220v or 240v can I put a Transformer with is less then the 3000VA say a 1500VA or a 500VA on this Inverter.

hi kabiru. i have used transformer (220v 12v), then bridge for dc which drives the 12v relay.
can someone help me with a 12v dc to 220v ac full bridge inverter circuit diagram. the first full wave rectifier(self oscillating eg irs2453d) is connected to the 12v supply, then a transformer, followed by a rectifier, then the other full bridge rectifier.
Can someone help me: I am building a 1000W full bridge inverter using 2 self oscillating full bridge drivers IRS2453D. The first irs2453d converts 12v dc at high frequency of 10kHz to 12v peak to peak, then a transformer to step it to 220v then a rectifier to get 310v dc, and finally another urs2453d to get 220v ac. 1. What (...)
I am a complete novice at electronics but like to fiddle. Any way to make this 220v bulb work on 120V or can I just use the LED Panel by itself with a 12v power somehow by cutting the wires to the board and adding a resistor. It has 145 LED bulbs. Pics attached thanks. 5602256023
i have the following schematic for 50hz 12v to 220v dc. i have foud it from internet but not yet tested it. The problem is that how i can adjust pin no.2 the duty cycle by giving feed back from output 220 to obtain pwm? does it only require modification on the pin 2 or whole circuit needs to be changed? 58210 [ATTACH=CONFI

Hi I want to ask is it practically possible to boost 12v dc from a battery to 220v dc? If yes can you help me how?
Dear Sirs, can somebody explain me how does this circuit work? I'm aware of how an SCR works but i don't understand how the entire circuit works. Thank you in advance
PFC stages are generally boost converters, otherwise they couldn't sink a continuous (sine shaped) current for all instantaneous input voltage levels. A 60 to 220v boost factor doesn't give best efficiency, but should basically work.
You probably have a 50% duty cycle. This explains the doubling of the voltage. You shouldn't attempt to use a boost converter to step up 12v to 220v. Duty cycle will be tiny. Peak current will be huge. Better to use a push-pull converter with transformer or any other suitable transformer-based converter. The inductor you used is too small. It burns
