A system controller includes: a first signal processing component configured to receive a first signal associated with an auxiliary winding of a power conversion system and generate a second signal based at least in part on the first signal, the power conversion system further including a primary winding and a secondary winding; and a drive component configured to receive the second signal and output a drive signal to open or close a switch to affect a current flowing through the primary winding. The first signal processing component is further configured to: detect a plurality of valleys of the first signal, the plurality of valleys corresponding to a same demagnetization process of the power conversion system; select a valley from the plurality of valleys; and change the second signal at the selected valley."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for regulating power conversion systems operating in quasi-resonant mode","description":"Systems and methods are provided for power conversion system regulation.
