The power supply circuit is provided with a first power supply circuit including first and second switching devices, a second power supply circuit including third and fourth switching devices and a switching control circuit. The switching control circuit controls the switching devices so that the first switching device and the third switching device are turned on and off at timings different from each other when an alternating current voltage from an alternating current power supply is positive, and the second switching device and the fourth switching device are turned on and off at timings different from each other when the alternating current voltage is negative."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply circuit","description":"This invention offers a power supply circuit that is capable of improving a power factor as well as reducing a ripple current of an input/output of the power supply circuit due to switching of a switc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8536843","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.
