Hi everyone, Can any body present here may help me in understanding and making a UPS based on SMPS AC to DC converter so that there will be no need of any type of transformer and the UPS would not be bulky and heavy. It should handle be capable of handling atleast 500Watts of Power. Thanks in advance
Can someone suggest to me a multiple input AC to DC converter module or chipset that converts 220vac to 5Vdc. The scenario is this, in a control panel, there are lamp indicators that lights up upon completion of each process (flood control process) i need to detect each lamp indicator as it activates so that I could remotely control each device
Hi good day. I am using some 6Volt batteries that you can pickup at walmart, to get either 12V dc or 18V dc. I was wondering if there is a way to achieve the same outcome using an AC/DC converter. When I search the net looking for a converter there are just too many to understand what will work similar to 2 or 3 6Volt batteries in series. Any idea
hello i need sch about AC TO DC converter with ICL7107 ,please help me. thank you
hai, i have a an ac to dc converter with 3 switching frequencies 100Khz(power factor and harmonic correction),230Khz(primary of dc to dc ),460Khz(secondary of Dc to dc ),I have trouble in choosing the input/EMI can i choose a filter for this module please help
Hi All, I am looking for really small ac to dc converter(would be really good if its made using cmos process) that can operate at 13-19 Mhz and can provide output voltage of 2.8 volt.

hi .. I need a simple circuit for AC to DC converter of 220 V AC to 15 V DC (current rating: 3A) using a transformer for charging my VRLA batteries. Thanks in advance
1. For AC-DC conversion, the ripple is difficult to compress. But in DC-DC conversion, that is easier. 2. Telecomm equipment always use -48V DC, that is safe to human body. But AC, say 110V or 220v, is dangerous to operator.
Hi, Can anyone tell how the isolation come into picture in the case of ac to dc converter? what is use of the ground pin int the ac power supply? Is it any way related to isolation which is coming at dc side of ac to dc converter?

i have a moderate electronic circuit background im building a electric vehicle from a 1974 VW beetle and i had a idea to help me drive further, i wanted to take a small 110v AC generator and convert the AC to DC and then regulate it to 98v, i need the circuit to handle at least 1000w, it doesnt have to be a perfect DC signal, just enough to cha
Hello, Working on design - inverter for 3 phase induced motor 380VAC x 3 I am using IGBT module (rectifier + 6 transistor) that convert the 3 phase to ~537.4VDC = 380 x 1.414 I need from that voltage 537.4VDC create lower voltage for the control section - 15V + 3.3V Isolated one option is to use flyback trasnformer with multioutput with i
Hello everyone, i am making a wireless charger for my phone. I need to fit a small ac to dc circuit in my phone's back(<1mm). I can't find small diodes ( i need to convert 5v, 1a or more). Can you post a schematic with small parts ? Thanks.
Hi everybody, I need some help, I need a capasitive circuit that converts 220v AC -to- 5V DC . Can you help me finding this? Or can you give me an idea to construct the circuit? Thanks a lot..
As already dito, the perfect way is to change the primary of mains transformer from 110 to 220v, and I know this is not expensive. I think any other CHEAP solution will carry noise, or something else not very good. Good luck

I need a circuit to convert the 220v ac to 5v dc. 1. Is there any better alternate for changing the level of voltage instead of transformer? 2. I need a very smooth dc. (No matter how big the circuit would be!) 3. what should I consider for Impedance matching?
If you need very low power you can do by voltage multipliers , Other wise you can run a 12v DC motor coupled with a 300V DC generator to get the output. That is the only way How do you mean only way? Can you elaborate and give us some light on this? What you will get if you put Graetz bridge on HV mains (
Hello All, I don't have 5V, 5A power supply adapter (AC to DC ). I have 12V, 3A power supply adapter. my current requirement is 5A at 5V. So, can (12V,3A) adapter replace (5V,5A) adapter? because 12V power supply adapter has only 3A current capability & i require 5A current & 5V. this adapter will be used to source the power to step dow

hii, I am working for a project and the basic goal of this project is to make AC to DC rectifier with 4 NMOS devices. There has to be a pulse generator for NMOS biasing within few neno second (just like PWM). The output of the rectifier has to be about 15 V. I have tried a lot to design it, but failed... Plz help me.
i want to build a dc to dc converter with input of 90vdc to 12vdc @2.5 amp
It depends on the application. If the 220v is AC mains, the current is low and you don't mind the health risk, you can do it with two resistors. Otherwise I would suggest a 220v to 5V transformer is the best solution. Brian.
Hello All, I want to use a DC TO DC converter to supply 3.3V for a high speed design, usually I put a linear regulator (LDO) after the DC to DC converter, but in this case this is not possible because I will exceed the power budget. I find two DC to DC converter with an output voltage of 3.3V and the required current rating ...., but (...)
hi all my friends! i want to know ,how can i convert 5V ,500A (AC) to DC.please help me!!! thanks!
please suggest me 5v to +/- 15v dc to dc converter with driving capacity of 4 amps isolated output.
Hi, There could be a better solution, but you could try this. First convert the 220v AC to DC by means of a bridge rectifier. Filter this. Then have a power stage with 4 MOSFETs/IGBTs driven by a control section that produces 2 outputs of 400Hz that drives the MOSFETs/IGBTs using hi-lo side drivers. Adjust the duty cycle as required to get 115v a
