For the last one and a half year I have been trying to design a MPPT controller for my solar panels. Most of the time has gone in to learning electronics and especially mosfets, mosfet drivers and inductors have proven to be a tough subject to grasp.
I will show you my latest attempt at mastering this project.
I will show you how I create a DC motor controller. It will allow me to change the speed and direction of the motor.
This drawing here shows you the basic structure of the project. The potentiometer controls the PWM generator to change the duty cycle. This signal then goes to a h-bridge made of two IR2110 mosfet drivers and four mosfets. The switch controls which combination of mosfets get the PWM signal and by doing so determines the direction of the motors rotation.
