hi i need sg3525 based pushpull converter design examples (transformer, mosfet,etc) pls.................... satya :idea:
The sg3525 is simply a PWM chip, not SPWM. Keith
The output from this IC is a square wave, so if possible use ICs which can generate sine waves, for example MAX038 .. However, there is another option .. If the output frequency doesn't change much you can consider a multi-pole passive/active filter connected to the sg3525 output .. This filter should filter out most of higher harmonics and the
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 using a pus
Dear Goldsmith thanks for your patience and the enthusiasm to help. i will try and break my need down as close as possible. i am trying to build an iverter using the sg3525 to drive a ferrite in push pul configuration and generate a voltage of 325 dcv at 5khz. then i am going to use pic to generate sinewave in fullbridge mode at about 5khz. so m
I could not find sg3525 for Proteus. Proteus does not have any component sg3525. And I could not find one after searching Google. Does anyone here have one?
hi guys, I intend to design an inverter using sg3525. the problem i have is how i could connect the low voltage disconnect, set frequency at 50hz and control the output voltage. can anyone send me a circuit diagram that can help me achieve this on my email; oduoridave@gmail.com thanks in advance.
Hi guyz, i'm having problem related to sg3525 feedback.i've made a circuit but don't know how i can implement the feedback circuit.please help me.output voltage is about 24V.
I am into inverter design, I noticed that when a fan is connected, the speed is usually low. My oscillator is an sg3525 IC, I have seen several designs using the same IC with same configuration but when a fan is connected, it rotate very fast though still buzzing, I removed the filter cap from the other design but the speed (...)
Hi, iam new to this forum so i would like to say Hi to every one on this forum. I have been trying to put together a inverter with little success. first i put together the design made on the tahmidmc blog in this blog he explains every thing related to the des
Hi guys, I need some good ideas to design a rf mixer in the 10 - 12 -14 GHz frequency range with an If signal at 70 MHz. I try to simulate a ring mixer in microstrip line whit ads 1.5 and mwoffice but not with good result. If there are any body that knows any microstrip line mixer structure please help me!!! Thank you

Anyone designed a circuit for CCD array to ADC? Looking for advice or ref design. I am using a sony ILX5xx series 5k pixel CCD, need to do an A/D conversion and get the digital data out. thanks Ahgu
I recently have a request to design high-voltage analog ICs (Supply voltage at +5 and -70 Volt). I don't have much experience in this. Particularly, can I use voltage below the substrate voltage (substrate at ground potential)? What are the design rules regarding transistor sizing, width of metal layer tracks, etc? Anyone has experience in this? An
Hi, I want to ask all the analog ASIC designers here if they have some nice formular collection and cookbooklike papers how to design different flavors of opamps (from 2-stage till full-swing class ab outputs). I know the book from holberg and gregorian - what i'm looking for is more complete formular collection (for example also for class ab am

Hi all Does anyone perhaps have a tutorial / overview of software radio design? I am especially interested in the DSP demodulation parts. I have found some pdf's but they are not suitable for newbies :smile: tnx in advance ***************************************** Please don't reply unless you have useful information to add on this post.T
Hi folks, I'd like to design and build a home-made simple audio switch in order to expand the number of possible input sources for hifi equipment. I thought of simple analog MPX like 4051 but I'm aware of possible signal quality issues (noise, distorsion...), not only with the IC but also with the pasive parts: PCB paths, conectors... Any piec

Hello all, I'm trying to design a lowpass Digital Chebyshev Filter IIR to get the average of sinesoidal wave with some cut's from a triac. To do that I try to use Filte.r Solution.s but if I specify 10 sig bit (to use a 10 bit ADC of 16F870) I get saturation on the filter ... Some one have tips to do that. Thank's NeuralC

The reasons for this forum existence are 2: 1. I think it is about time that Elektroda have an exciting knowledge base for VLSI/ASIC design. 2. I think that we (electronic professionals) had enough with me too's & proggies requests spams. It is time to learn & exchange usefull design info. Thanks all for participating - I hope this forum will

Hi Before simulating VHDL code behaviorally (we use Cadence Leapfrog VHDL) that is intended to be synthesized eventually, first get it to compile with Cadence Leapfrog (because we have many licenses for that), and then read it into Synopsys (only the Synopsys 'analyze' or 'read' command is necessary, you need not synthesize the design to get the
