Hello Everyone,
Hi,I am new to website and new to this subject aswell,so if my quetions ar silly please bare with me.
I am trying to build Three phase H bridge,using 6 mosfets to commutate Three phase Bldc motor.Voltage supply for this motor is 15v-60v DC and i am using Atmeg8 microcontroller to control it.
My questions are related to H-bridge:
1) How do i choose MOSFETs?
i have build a H bridge using 3 p-mos (High) and 3 n-mos(mlow) using driven by four switching inverters made by transistors.
2)IF i build another h bridge with all n-mos will it giv me same results?
3)i have also consider using L6385 driver,would that make any diffrent?( by the way i havent figured out how to use it tho)
4)when it comes to H-bridge and drivers,how to decide which one is better refer to cost,efficiency and avaibillity?
