The controller further includes one or more comparators configured to compare a current through the power converter to the peak current reference and the valley current reference, to turn a gate switch of the power converter on when the current through the power converter falls to the valley current reference, and to turn the gate switch of the power converter off when the current through the power converter rises to the peak current reference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hysteresis controllers for power factor correction in AC/DC power converters","description":"Methods, devices, and integrated circuits are disclosed for controlling a power converter.
