The power supply device is provided with a precharge circuit for reducing the current from the battery and supplying the current to the capacitor. A control unit of the power supply device first supplies electric power from the precharge circuit to the capacitor, then sets the main switching unit from a state of disconnection to a state of connection, and stops the supply of electric power from the precharge circuit while the state of connection is established."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device","description":"A power supply device, provided with: a battery; a capacitor connected in parallel to a load; and a main switching unit capable of switching between a state of connection and a state of disconnection ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11469687","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.
