This article gives 2 main disadvantages:
- Variable frequency
- Requires ESR on the output cap
Is variable frequency a big of a deal? Why would synchronization matters for a converter?
And why are high ESR necessary for it to work? What I'm missing here?
I ask this because I've been working on a boost converter with hysteresis control as a Uni project, and I've found very little resources or interest – giving me the impression that either the solution is known and considered bad, or that is unknown but not worthy of research.
Is Hysteresis control undesirable? What makes it so?
