Abstract
A quasi-resonant (QR) converter introduces soft transition for valley switching and valley locking. One exemplifying QR converter is capable of performing valley switching, but has the valley switching in a specific signal valley of one switching cycle softly transit to the valley switching in another signal valley of a later switching cycle, via at least one switching cycle performing no valley switching.
