frnds i wana know whats the difference in application of a five pin and four pin input ferrite core transformer? (in four pin two are for primary and two for feedback but what about the fifth pin ?). i am using a four pin ferrite core for an inverter but it out put is less. how it differ from each other (...)
If you live in low temperatures area the ferrite core (known as inverters) are best (in my opinion and experience) and if you live in high temperature area I may suggest to go for Iron core Transformer. Quality means much in every product type.
It's just a vendor specific type marking, not containing any readable specification. Mechanical core dimensions are probably the only information you can get without unmounting the part. I don't exactly know what you mean with a "two-pole ferrite core". Is it an EE or EI core shape? Refer to major (...)

A mains transformer is designed for 50Hz or 60Hz and some work poorly at 6kHz. Audio transformers with good high frequency response are bifilar wound. Your PWM frequency is low enough to be very audible and causes the filter to be poor. Manufactured pure sine-wave inverters use a much higher frequency that cannot be heard and a small transformer
Please look at the attachment and suggest the better way to modify the schematics of the inverter for more power.The inverter schematics is for 12v to 220v 200 watt inverter with ferrite core transformer. I need to modify it to go for 500 watts. how can i do it? two more trafos. more mosfets at the output. (...)
It is an SMPS design. It is a 2-stage converter. Instead of standard bulky iron core transformers, ferrite core transformers are used, that work at high frequencies. They are much smaller than the regular bulky iron core transformers. Since they only work at high frequencies, the high frequency AC is converted to DC and a (...)

welder allows you to weld with current from 20 to 100A, by electrodes theoretically to 3,25mm. Practically the best results are gained at electrode to 2,5mm. Dimensions of the welder are really small. Everything was closed in a housing of 78x120x165mm. The welder operates in a
You can't even decide, which cabinet to use considering the requirements and components in use until you describe details and layout. Similarly is the case for transformer. Is it iron core or ferrite core? What is the operating voltage? A single winding or for push pull, half bridge or full bridge drive? Want to make your own or use a ready (...)
This would typically be a small ferrite core transformer. The numbers 4:50 are to indicate the primary to secondary ratio. In other words, for every 4 turns on the primary you would have 50 on the secondary but the article doesn't mention exactly how many turns that would actually be. It's just a guess but 4 turns sounds too low so try at least
Hi..... all..... I Need Datasheet for old (CRT TV) TDK ferrite Transformer(EC40) ...... I want to remove copper wire and useing for a CDI BY UC3845 system;-) (
The frequency of your PWM is much too low (only 1.5kHz) so the filter does not do much. If the LC filter is -3dB at 250Hz then there is plenty of output at 1.5kHz, 3kHz, 4.5kHz and many higher harmonics. If the PWM frequency is 30kHz or more then the filter can remove the 1.5khz fundamental plus all the harmonics but you might need a special high
But in that thread i didn't find the solution. All the people are saying that design is having lot of problems. And also i don't have knowledge about micro controllers. So please tell me the possible solutions. Circuit is working fine except charging topology. Charging current is constant and can adjust with trim pot. At

I need help on pulse width modulation scheme that is used in converter. How it is implemented in inverter circuit and DC to DC converter circuit. Hello, PWM ( Pulse Width Modulation )... much like a CHOPPED square wave.. either single-ended or push-pull... uses transistors/MOSfets ....driving a ferrite core transform
How to design a pushpull inverter transformer for cfl ballast of 18W output power from 12V input voltage and 1.5A input current generating 50V cfl Von voltage and 360mA at the ouput. According to frequency, output power and input power how the high frequency ferrite core is selected. The inverter is switching in 33KHz. (...)
You will not be able to make the full 230 vac sinewave with a 12v to 230 vac transformer but that's not the question. What type of transformer are you using, a high frequency ferrite based or low frequency (50 hz) transformer. If using high frequency you need a good L-C output filter design based on maximum peak 50 Hz current so filter coil
am tellinh about iron core , and what is the benifit of ferrate core ? And how can we simulate dsPic30F through PC , ? any software? By using ferrite core, you can make a 2-stage inverter, where the first stage (the stage employing the ferrite core) steps up the (...)
Hi I am trying to control single phase inverter using TI Tms28335 microcontroller, using its development kit (control card and a docking station ) via code composer 3.3. However when the dc link voltage is increased to say 100V , the connection between the pc and microcontroller gets disconnected. TI people mentioned it was due to emi and i sho
they have Mhz piezo drivers that run off hundreds of volts in pulses too for imaging. But if you use two inverter buffers and drive differentially that will double your output. Again a simple small coil winding around ferrite core with a tap for primary will boost signal significantly. They use this to make piezo alarms with
You shouldn't attempt to build an inverter without a transformer. If not anything else, it'll at least provide isolation. What I think you want is a design without using bulky iron/steel core transformer. What you need is not a transformerless inverter, but an SMPS inverter. You can find a basic block diagram here:
Hi Reza At first you can use an SG3526N and two mosfet driver ( e.g IR2113 ) you should design an H bridge with it , to achieve high voltage ( 311 volts DC ) . i think 120KHZ would be good as PWM frequency . at first read the datasheet of SG3526N . and tell me can you design first stage ? By the way , are you familiar with inductor and ferrite
Hi, Im designing a DC to DC converter using a push pull topology, I know I need a centre tapped ferrite core transformer connected to two power mosfets to get a higher output voltage! the problem is I cant find such a transformer on the market! is it ok if I use a flyback transformer instead? PS. I took out a EC28 Transformer form an o
HI for all Iwant to build swich mode power supply with Full bridge design using irfp460 (4 transistors) and TL494 pwm And ferrite core ETD54 n27 frequency 80Khz And with current adjustable and I want the circuit without driver transformer for mosfet Gate Please any one help me for build the circuit(without driver transformer)!!!!!!!!!!!!!!!!!!!!!!!
TRANSFORMER LESS inverter IS NOT PRACTICALLY POSSIBLE. IF YOU WANT A SIMPLE DESIGN IT WILL NOT BE POSIBLE WITHOUT BULKY 50 HZ IRON core TRANSFORMERS. IF A WANT TO USE A ferrite TRANSFORMER THEN THING WILL VERY DIFFICULT TO HANDEL FOR A HOBBIEST (BECAUSE YOU?RE QU
one option wold be a Cockroft walton voltage multiplier ckt. assuming an input supply of 230V or 110 V the supply must have some kind of step up transformer to step up the supply to al least 4 or 5 kV. the next stage would be 3 or 4 stage a cockroft walton voltage multiplier which would give a output of 13 to 15 kV. CW type of supply can not have
One of my friend gave me an emergency light with 11 watt CFL (AS shown in the photo) which operates with an Push pull inverter circuit powered with 6 volt 10 Ah battery. It has a peculiar problem which he coudnt solve. Initially the tube was blackened, and i replaced it. Within 10 minutes i lost the tube due to blackening at the ends. I tried with
Hi to All, I am trying to build an inverter 2kw running with toroidal transformer could any one help me to winding this transformer, also the power transistor should I used in this project. Note: the core for transformer is ferrite. Many Thanks
Hi, The power output depends mainly on the MOSFETs and the transformers. If it is low-frequency inverter ie, MOSFET to iron core trafo, then it depends on the MOSFET ratings and the wire and core ratings of the power transformer. If it is SMPS, then it depends on MOSFET rating on both step up and full bridge sections and wire and (...)
Hi, If you mean with no transformers, not even ferrite ones, then you have to first step up the battery voltage to high voltage (260-300v) using boost converter and then use H-bridge converter. I think what you mean, is, without heavy iron core transformer. In that case, use SMPS with a ferrite transformer. First step up battery voltage (...)
You set your frequency based on what you need your loop bandwidth to be (load step response) and what size of ferrite you can stand (physical size). Tens of kHz is so '80s. Maybe somebody was using a comparator with a sporty 1uS prop delay or something. Sine wave is going to get real jittery when you approach the crest or valley. I can't think o
it is to small and switching frequency is also too small I don't know what switching frequency you are planning, but the application suggests a frequency > 20 kHz. The core size will be selected according to switching frequency, power and inverter type. Manufacturers have usually overview tables or calculation tools for the selecti
