Thanks for your post. Well, first thing to say, I am from Philippines so I have a somewhat limited English and I am not sure if I understood everything you said correctly. Anyway, I can see that you're suggesting for me to use a PIC for the project. Am I right? Well, due to series of failures...
As far as I know, those two signals are complementary. So, strictly speaking they should not be identical. Please correct me if I am wrong. By the way, I get the basic concepts of my design from this link...
I have already posted this thread to the Power Electronics section. But I cant find a way to send you the schematic diagrams without showing it to everybody else. So I decide to show it here. This circuit below is suppose to be connected to a MOSFET fullbridge via IR2110. But as it turned out...

Hello everyone, I have found a lot of threads related to my query but it's exhaustive to be in everyone's conversation so I decided to post my own. I am now working for a university project (12 VDC-220VAC pure sine inverter...
By the way, I am doing it for school project and I have to finish it very soon or else I'd be disqualified for graduation. I only have three weeks to finish everything but I am willing to do it day and night. What I am saying here is, this is a very important project for me. It's like the rest...
Wow, I can see you're sharing much. Thanks a lot. Would you mind if I send my schematic diagrams to your e-mail? You might want to criticize and improve it. I cannot share it here because the schema is not my intellectual property. It is someone else's. So I am sharing it only to those I can...
I want to restrict my design from using microprocessors. I had an encounter with someone who constructed an inverter without the use of those, so I am thinking it would be possible for me to do it. My present design's basic principle is this:
sine oscillator ---> SG3524 (it has internal...
So you mean SG3524 is not a good tool for sending signals to control the MOSFETs? Can you tell me how can I have a good controlling method using inexpensive materials and simple circuitry?
By saying adding the deadtime externally, do you mean adding resistors, capacitors, and diodes for both the Hi and Lo input signals? Can you please enlighten me more about using software to generate Hi and Lo signals? Havent done it yet.
Hello everyone, I have found a lot of threads related to my query but it's exhaustive to be in everyone's conversation so I decided to post my own. I am now working for a university project (12 VDC-220VAC pure sine inverter design). I started learning about inverter design just a few months ago...
are you referring to rcd deadtime? did it. but no good. more deadtime makes the output wave less and less sine-looking so i have to limit the deadtime generated.
