The power supply device includes a control unit configured to control the semiconductor switch such that a voltage between AC terminals of the bridge circuit becomes a zero voltage only during a prescribed time period before and after two zero crossing points in one cycle of the input current and such that the voltage becomes a positive-negative voltage in which the output voltage is a peak current value during other time periods. Consequently, a power factor of the power receiving circuit is improved and a loss of an entire device is inhibited, and a size and a cost of the entire device may be reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device","description":"In a power supply device the bridge circuit is configured such that a plurality of series circuits of two inverse parallel connection circuits of a semiconductor switch and a diode are connected in pa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608539","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.
