Hello,
i am working on a project of grid tie inverter and there are some problem related to that,
1) For sampling mains sine wave i am using voltage divider from 220V to 2.5vpp is this a good approach or transformer and then vdr will be mor handsome approach? Plz clarify the drawback in first approach..
2)For testing purpose i used an auto-transformer and rectify it to 290VDC which is provided to the drain of Bridge inverter. Is this a correct approach ?or there will be a problem due to common ground of both inverter and control circuit.
Thanks alot
