Very important piece to reduce noise in switching

[@Dieseleux]

Ferrite bead on source pin are also very effective to reduce ringing, put inductance in the source, introducing negative current feedback at very high frequency and control the dv/dt of the mosfet at turn on and turn off. Also work to absorb high frequency like you say in this great video. The picture of the mosfet you show, have bead on source pin....

Hello, thank you for your excellent explanation

[@castlecodersltd]

Haven't seen those on an FET before. Thanks for enlightening me 🙂

Nice explanation with good illustration, really nice content. Your channel will pick pace, keep sharing high quality content.

[@Electronic4U-david]

Thank you so much 🙂❤️❤️

[@christopherleubner6633]

You will want that bead on the gate drive lead as it stops harmonics that can cause the mosfet to latch up.❤

The switch time shown in your oscilloscope picture is incredibly slow, compared to my experience in DC/DC SMPS (8 ns), but it looks like your circuits are in the AC/DC area, so you're working in KHz rather than MHz.

[@Electronic4U-david]

Hello, thank you for your valuable explanation. My equipment is a bit old. I try to update myself

Maybe better to have an AI speaker. I stopped listening after 1 minute. Wonderfull subject, executed badly.

Hello. I am really sorry for speaking badly. I try to get better. I put English subtitles (not automatic), I hope you will continue to support me so that I can present better
