So today i bought drivers and i have inverter up and running :)
here are some images of driver board
Setup, it's a real mess but hey, it prototype
And waveform, i know it isnt 230V, but im running it at reduced voltage becouse i dont have any capacitors on input and my psu is not happy about that hahaha
At the moment im using 330nF capacitor at transformer output, this is what i had at hand, with 5 uF there was huge backfeed into PSU, and voltmeter go over 60V and shut down everything. So now i have to tune capacitor and maybe choke... The important part is that it is working :) Program im using is 2×sinewave.
Tried softstart and its working perfect, also i tried to reset MCU while inverter is running to se is there any errors but everything is alright
