BLDC motor drive EMI Filter

Hello Ajay,

You can use this site for a low-pass Pi filter design: https://electronicscoach.com/pi-filter.html
Here is another resource from TI: https://www.ti.com/lit/an/snva538/snva538.pdf

Typically a low-pass Pi filter rectifies any AC ripples in high-voltage supplies, like a battery. This is generally used in automotive applications and we have a Pi filter on DRV8316REVM (BLDC motor drive <70W). See below:



Thanks,
Aaron
