A switching frequency of the first PWM signal is changed at a change time point at which a cycle of the first PWM signal starts. A length of a cycle of the k-th PWM signal firstly appearing after the change time point is shorter than lengths of subsequent cycles of the k-th PWM signal appearing the first cycle of the k-th PWM signal. This polyphase power-supply device has high reliability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polyphase power-supply device","description":"A polyphase power-supply device includes first to N-th DC-DC converters connected in parallel to each other between an input terminal and an output terminal and a switching controller configured to pe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11967904","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.
