Sine wave power inverter

[mat janssen]

Please let me know if it works and how you did it. And if you have some questions about the hardware, just let me know, maybe I can help.

Okay Matt,

That would be great. I need to design a RCD snubber and I don't know the maths may be you can help. I am concerned about the switch off peaks.
I would send you the entire schematic as soon as I finish it up. It will take some time but I will keep in touch.

As an aside... talking about Transformers... the 50 year Copyright (1953) has expired on the Radiotron Designers Handbook. I use this as my bible for Transformer Design and it's abosolutely brilliant - the principles in design are as valid today as they were back then. You can download it from the internet from various places (including the link below) - but be warned it's about 70Mb total pdf...

Most Transformer manufacturers have forgotten most of this stuff (and it reflects in the abysmal products they produce). So, if you're into rolling your own (or commercially designing), then you'll love this, if you're not, then it's a sure cure for insomnia.

Give me please some data about the switching frequency of the system and inductances of the transformer then I will sent you snubber data

Hi there,

Melanie thanks for the link. I live in a place where dial up is the only available internet. But I can manage to download it. Matt I would send you the details as soon as my prototype is ready.

Thanks guys for keeping this thread active.

You're lucky, they've broken it down into chapters so you don't have to be on-line for a week straight, just grab a section at a time each time you go on-line to do something else.

Im trying to download the CHAPTERS from the site.But it is extremely difficult to open.Going to home page most links are not correct and site is under renewal.Can anybody be please send link to mirror site(s)?
Thanks in advance.

Also please let me know if anybody has used transformer after the H-Bridge and whether the operating frquency of transformer supposed to be output sinewave or the switching frequency? In case the fequency is that of output,
then we loose advantage of switching and having small transformers like in smps.
