Dear,
I try to use IR2110 to drive the mosfet IRF840 and the problem is that as the mosfet is driven by a varying frequency, lets say from 100Hz-50kHz. Someone tell me that as the highside of IR2110 using the boostrap capacitor, so the frequency should be high and suggest me to use the lowside only. However, there is another guy told me that the lowside should be reference to the ground and my mosfet (M9&M10) source reference will be change continuously and it is not grounded definitely.
So i want to ask is that if i can still use IR2110 to drive the mosfet with its lowside or i need to replace it with another model? if then, can u pls give some suggestion.
Moreover, I need to find voltage transducer rated about 200-300V, 400-600W. But it is quite expensive, it cost a US$70 each. Is there anyone know there is a cheaper one in the market.
Thx for help!!
