Attached File  Capture.PNG   40.46KB   0 downloads [color=rgb(51,51,51);font-family:Arial, Helvetica, sans-serif;font-size:17px;]I am facing problems with my solar charger circuit using mppt. The main problem is the mosfet switching followed by the dc-dc converter. When i connect my circuit to microcontroller to give PWM at gate voltage drops across the solar panels. I am using a pnp and npn combination to drive the NMOS IRF540. Please help me with the schematic ..[/color]
