The switching power supply circuit includes: a switching circuit; an output capacitor; a controller; and an inductor short circuit. The switching circuit includes: a first switching element for voltage control; a second switching element connected in series to the first switching element; and an inductor connected to a connection point between the first and second switching elements. The inductor short circuit includes a diode and a fourth switching element connected in series to the diode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor light source driving device and projection image display device","description":"A semiconductor light source driving device includes: a switching power supply circuit that converts a voltage across direct current (DC) power supply into a DC output voltage and outputs the DC outpu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11252384","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.
