Hi,

I want to estimate losses while using the BLDC driver mentioned.I found this excel sheet for calculation.Do we have an application note to understand the equations provided in this excel sheet

Hi,

This excel sheet is used to compute the losses for BLDC Driver Mosfets during trapezoidal commutation.Are there any such tools available for FOC Control.How to compute the losses if FOC is implemented.

Hi Reshma,

Unfortunately I can only find one that is for integrated FET

I'll keep looking and update if I find one for gate drivers.
