The filter device includes a casing; a filter reactor housed inside the casing, for removing a high-frequency component; and a booster reactor housed inside the casing and disposed below the filter reactor, for boosting a voltage of a current having passed through the filter reactor. The booster reactor includes an iron core, a coil wound around the iron core, and a spacer interposed between inner and outer circumferential portions of the coil to form an air passage for passing air introduced into the casing. The booster reactor is stored in the casing so that the air that has passed through the air passage passes through a periphery of the filter reactor disposed immediately above the booster reactor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Filter device","description":"A filter device is electrically connected between a power supply and a power converter including a converter unit for rectifying inputs and an inverter unit for inversely converting outputs of the con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9691535","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.
