A method for controlling a voltage of a Bulk capacitor in the switching power supply includes detecting an instantaneous absolute value of the AC voltage; comparing the detected instantaneous absolute value of the AC voltage with a preset voltage; and controlling discharging and charging state of the Bulk capacitor according to comparison results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply and method for controlling voltage of bulk capacitor in the switching power supply","description":"A switching power supply includes: a rectifying unit; a Bulk capacitor; a converter; a monitoring circuit; a control circuit, controlling discharging of the Bulk capacitor, being configured to perform","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787193","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
