Circuit design for adjusting the electrical load of a small wind turbine (MPPT)

An ideal buck converter has no power loss, so if the output voltage is 20 V, the output current must be 2 A. Step down to 10 V, and the current must be 4 A. But if the load resistance is the same, how ...

Driving a P-channel MOSFET with high voltage input

I would suggest starting again with a completely new design; the problem is driving a high-side switch which is difficult to do. As part of a new design, I would consider using a power circuit where ...

Driving a P-channel MOSFET with high voltage input

Since you are employing a push-pull stage to drive the gate, which is presumably intended to overcome a few nanofarads of gate capacitance, then any resistance between the push-pull output and the ...

Driving a P-channel MOSFET with high voltage input

Any suggestion on how to drive the gate and limit the voltage so it does not exceed Vgs? Try these modifications first: - R6 was 10 Ω and would have been the main reason why it and the Zener got so ...
