I am working on bldc controller, I knew that flyback diode should be used across the mosfet( drain to sourse).
1. But how can I choose the diode, is in4148 is enough? 2. And for mosfet's gate protection ,can we use zener diode across gate to sourse?
3. And for ir2110 , diode parallel with resistor is enough? For ic protection from mosfet.
4. Inverter circuit has 3 pairs of mosfet's ( high and low), each pair gives output phase for bldc motor. What should be kept between the mosfet phase and bldc motor phase?
5. And Is optocoupler is better to use on micro controller output to gate driver? Or any other method is there for controller protection?
Sry if I am asked anything wrong, advance thanks
Motor spec:
36v 10amp
