There is a lot article on this regards. And I try to follow there directions. But I stuck with LC filter. Can any one help me on this regards. I enclosed my H-Bridge circuit. I vision is to generate 50~100 Watt Inverter (220v, 50Hz) sine wave ac from a DC 12V battery with SPWM Technique.
I used [URL="ta

Please let me know I make this attached circuit for ATmega8 based voltmeter but reading is displaying
only first one rest of the two digits are not standing they are up/down fast.And if input DC voltage
the voltmeter shows good display.

Please let me know how calculate LC or RC values of filter use inverter.Let suppose if transformer`s secondary is 220v 50 Hz @ 2 Amps,
and primary 12V ,so how to choose or calculate filter values and how to know the number of harmonics present in the secondary.
If inverter`s output is modified square wave of 50 Hz.

What is the best way to convert square wave into sine wave in an economic way? Project must have to be micro-controller based(PIC)
1. 220vAC/50HZ (square) >> HVDC >> 220v AC (sine)?
2. Using LC filter?
3. Using sine oscillator?
Note: power ratings will be 1.0-10.0 KW/ 220v AC / 50Hz. No-load loss should be < 5W. (...)

Can anyone tell me how does the following circuit work?
i've used it in a project's power supply to convert 220v AC to 5V DC for use 5V DC to ATmega16 and servo motors ,
(ATmega16 and a servo are connected parallel) ; will the parallel connection

If you want to generate from 220v AC. First, please use a full-bridge and LC filter to rectify it to a croase DC. Then use a flyback AC-DC converter to generate 50V, 3A output.

I need your help to convert 220v 50hz to 115v 400hz. Its for an aviation project. I really need some advices abt how to reach 400hz from 50hz. I searched for frequency converters but couldnt find any circuit schematic. I need build it my own. PLease help me

I am designing 220v,4Amp DC supply using full bridge rectifier. I am using auto transformer after that isolation transformer to get variable DC voltage at output. I kept two 470uf capacitors as filter. but for 123V rms input i am getting 155V DC voltage as output. How it is possible for a low voltage ac , getting hi

I want to do communication on 220vAC, so I am need of Power Line Transformer PLT, I am not able to find it over here in my local market. I have FSK signal which I want to send on 220v AC. I came across some transformer spec, they include 50Hz blocking capacitor for 220v that's the high pass filter. It blocks the 50hz (...)

I need the surge & noise filter for 220v AC schematic
I wont to use this schematic with my computerize attendance control terminal because I am facing the problem in terminal mostly the data is lost due to surge
So please provide me the best surge & noise filter circuits
