Hello.
I have just gotten into sinewave inverters because I want to build such a device to power certain labb equipment in certain situations(and I simply want to learn more about these sort of devices).
I have chosen to skip modified sinewave inverters all together and I understand that there are a few different ways to realize a pure sinewave inverter.
I just finished reading this PDF document in which the go over the design of a pure sinewave inverter(hens forth called a inverter) based on analog circuits. It is designed for creating 120V 60Hz and I need 230V 50Hz, in any case the designers in that document didn't really complete the design because it failed in certain aspects and they didn't have time to prove that there solutions will work but I'm sure they would if one was to follow there recommendations.
But that design completely lacks a circuit for stepping up a say 12V DC source to a 170V DC source which they needed to drive a H-bridge to output a 120V sinewave.
In any case I was thinking that it would be nice if one could enable more than one input DC voltage level, but I am getting ahead of my self.
I have also seen designs using microcontrollers and other fancier ICs, and the design I linked to is very simple but not really as good as I want and the more complex designs I have seen have been good enough but way more complicated than what I like to do.
If I asked you, "what do you think the most straight forward approach to designing a pure sinewave inverter to convert 12VDC into 230VAC 50Hz is?"
What would you answer?
Regards
