The converter is making very powerful high frequency noise (after one hour near the kit close the the computer, it hurts my ears badly).
Any idea to reduce the noise ? Is the inductance responsible for it ?
I don’t know if this is related, but my duty cycle suddenly jumped from very stable 65.4% to 69.6%. Perhaps temperature related.

Edit : the duty cycle variation is clearly temperature related. Blowing air on the converter parts get me back to 65%.
