    12VDC to 230AC or 230Ac to 230AC

    Hi everybody, Has a 12Vdc-230AC or 230AC-230AC inverter project already been discussed on the forum? Thanks.

    Hi All ! This is the revised PCB V1.4. I resized some components, C17 (soft start) wired properly, add FAN supply as suggested by Sylvio. Gerber on request.

    Hi all ! @Silvio : This is the edited schematic diagram of your SMPS. If you see any mistake, or suggestion, please let me know. Note: MCR100 Thyristor is now obsolete, i suggest S6X8ES as replacement. https://pdf.lu/2UnY (revised schematic)

    Hi All ! @Silvio I would like to redraw your circuits and make my own PCB. Please, what is the material core and size of ring for the S/C Protection transformer (80/1.5) ? Thanks. Steven.
