The power management chip is respectively connected with the output end of the first photoelectric coupler, the output end of the feedback circuit and the primary coil of the transformer. After the first photoelectric coupler is powered on, the starting circuit is turned on, and the power management chip and the transformer are started and work. After the first photoelectric coupler is powered off, the power management chip stops working and enters a standby state. And at the moment, the standby power consumption of the power management chip is equal to zero."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Starting circuit of switching power supply","description":"The disclosure provides a starting circuit of a switching power supply, which includes an input rectifying and filtering circuit, a starting circuit, a transformer, an output rectifying and filtering ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11502598","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.
