I m actually reading a section of a book which talks about parralleling MOSFETs. The book talk about "Power supply design". There is a sub section which describes how to design the circuit layout. It finally say : "Finally, to prevent oscillations with paralleled MOSFETs, resistors of 10 to 20 Ohm or ferrite beads should be placed in series with gate leads".
I'm surprised ! I have never seen a power MOSFET oscillates... And I actually do not understand what it means by oscillations. In which case oscillations happens ? And why when we parallelise MOSFET we increase the risk of seeing oscillatons ?
Thank you very much !
