HFI optimisation with increase in switching frequency

Hi there,

I have optimised HFI parameters for a 12 pole 14 magnet BLDC motor at a switching frequency of 25kHz, but when I increase the switching frequency to 30 kHz I can't seem to find any parameters that enable the HFI to run smoothly, is there another parameter I need to modify?

Thanks
