The DC power-supply device includes a rectifier circuit, a reactor connected to an input side or an output side of the rectifier circuit, a first capacitor and a second capacitor serially connected between output terminals to a load, and a charging unit. During a cycle combining a charging period and a non-charging period of a pair of the first capacitor and the second capacitor, the charging unit is controlled so that a charging frequency becomes 3n times (n is a natural number) the frequency of the three-phase alternating current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DC power-supply device and refrigeration-cycle application device including the same","description":"A DC power-supply device that suppresses an increase of a harmonic current and deterioration of a power factor without causing any imbalance among respective phase currents, in a configuration in whic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9692289","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.
