Solar charger schematic using mppt Answered

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 MSP430 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 ..


The voltage WILL drop on the panels when you load them with your circuit ! What ELSE can it do ?

That schematic is hard to read.

Does the circuit work in your circuit simulator but not when you build it?
