In DCM, I P goes to zero, and the diode stops conducting, whereas the power-switch turn ... the one that self-supplies the controller and gives the demagnetization signal—in forward mode. The reason ...

with extensive shielding and line filtering to keep undesired signals from contaminating the clean noise signal. A limiter is also an essential component: should the diode’s filament break ...
