I need, for car audio applications, the schematic of a DC/DC Converter from 12v to 48v (about 800W). Someone can help me?
Hi, How to control a 24V LED Driver (Green) dimmer with precision (brightness range:most Brightness to turn off). Can using MOSFET to design it?? Or using another component to design it? Another problem is how to using op amp to step up 12v to 24V?? I try using 741 op amp can't do it, so another op amp can do it or not?? Thanks!!
Go to this site: There you will find info on 12v-120V inverter. The only thing you will need to change is the output power transformer which, in your case, should have HV winding for 220V .. Regards, IanP

Hi there I want to design and build a DCtoDC converter to boost 12v to about 20V. I am a bit rusty with my basic electronics, could anyone help or suggest a circuit. Also, it would be great if the output is slightly variable. Is there a IC that i can use or a circuit floating around somewhere? The output need not be 100% stable. I want to st

Is there a solution to step up from 5V DC to 300V? Or 12v to 300V (DC)? I found something on this forum as Flyback Inverters... I want to use it to power my CDI.
as the title, I am designing a push-pull DCDC 12v to 400VDC. Before I start winding the transformer, need to make some decision of how to regulate the 400V. I can find many example schematics of AC to DC where the DC voltage is lowish using the TL431 and opto feedback......but not the other way
I need a simple and cheap PSU circuit to get around 15V from a 12v supply. The circuit does not need any fancy smoothing etc, must use cheap capacitors etc. No expensive chips or inductors. It only needs to supply a maximum of 1A and nominal around 400mA. But I must stress the circuit use the least amount of components and must cost less than $2
Can anybody help me for 12v to 220v 5kw inverter circuit diagram.
hi.. im looking for a complete circuit diagram of an 12v to 220v inverter please some one help me.. thanks..
Here is my contribution to the forum community. These work in Multisim 11 but I have not yet soldered them up and tried them for real. The +12v to +18V booster circuit is actually a voltage doubler circuit but with an added 18V zenner diode on the output to limit it to 17.9V or there abouts. Change the zenner diode and you can change the output v
Hi, I am currently building Push-Pull converter 12v to 315V 600W 50kHz. I am trying to use UC3846 controller as it seems like properly designed circuit is very robust. I hope someone can help me finding PSpice model of the UC3846(or UCx846 or UCx856) chip, or even better if someone has similar simulation completed. Thank you very much in advance
I want to make a sine wave 12v to 220v inverter with 25 to 50watt output. please send me the circuit.
Sorry, i have never dealt with a switching regulator before. Need expertise advice so that i won't end up buying the wrong IC chip. The current rating is 1A Is there any chip that provide an output voltage of between 5V to 5V? You need 5V to 5V or 12v to 5V regulation?

Hi, I need to repair a 12v to 240V 1500W inverter connected to a 500W water pump. Lately I am hearing that the pump is not working smoothly as it should. It seems the current is not continuous and smooth. The pump can be heard changing speed sharply in short instants. I will give more info later when I get the inverter and test it mysel
Hello all! I am designing flyback converter with input 12v (car battery) to two outputs of 5V and 1A per output, basicly car cell phone charger. I chose LTC3803 controller and first make simulations in LT spice, and all goes well with perfect coupling but when i include leakage inductance voltage drops are big, on full load voltage drops to 4V. i
hello, i have made an inverter using cd4047 as per the circuit diagram i have uploaded here.. as per the circuit diagram gate pulse are given to the mosfet from pin 10 and pin 11 of the IC . but when i apply 12v to the ic i am getting 12v at pin 10 but not getting any voltage at pin 11 but i am getting 12v from pin 13 so i have connected (...)
would there be a problem if I use two different AC wall adpater and connect their output in series to obtain a desired voltage to charge the battery? I have a 12v adapter and an adjustable AC adapter. One is 800mAh and the other is rated at 1.5A. My charge current will be under 800mAh. My battery requires 19v but there aren't a lot of cheap
I think the item you require is in-car dc-dc converter (12v to 19v). It is sold in computer shop & used to charge Laptop in a vehicle. If you're thinking of building one yourself there's quite a number of projects available in the Net. One using the MC34063 or the TL494 are quite common.
Convert to use laptop in car. Thanks a lot

Hello everyone, I'm Attempting to convert a Playstation 2 power supply from a single rail 12v supply to a 2A constant current supply to drive a stepper motor. I have been unable to find a circuit diagram for the item but I have been able to deduce a few things. ( If anybody has a copy of the circuit feel free to let me know :), ) I have worked
Witch is the easyest way to make a dc dc converter from 12v to 40v? Thanks.
first of all to convert 12v to 230V the amperage should be high enough.. Although it is 12v it should be about like 5 to 10 A. Now use a chopper circuit to convert DC to Intermittent square wave of 50 Hz/60 Hz. Then you can use a square to sine wave converter to smooth-up your output for a perfect phase lag between V and I. La
Hi, I'm trying to convert a pulsed 12v signal into a constant 12v signal. The circuit pulses several times a second so very quick. Can you tell me what sized capacitors, resistors i'd need to do the job? I was going to run the cap/resistor in parallel to flick a relay coil. to switch 12v line from a 12v battery. (...)
Is it possible, using resistors, to drop its voltage from 12v to 5V? What resistor(s) should I use? If the current consumption of the 5V input is constant you can use a resistor, but I doubt it very much .. By the way, do you know how much current will be drawn by that input??? and combined current by 12v pin and 5V pi
i really wanna design a flyback converter with a 12v car battery and to develop a 200v output..please help me guys........i badly need sm help if u hv any example designs please gv that to me...bcz it wd b a big help :(
