A plurality of second switching elements forming the second inverter unit each have a lower ON resistance than a plurality of first switching elements forming the first inverter unit. A controller is configured to switch on and off the respective first switching elements at a switching frequency higher than an electric fundamental frequency and switch on and off the respective second switching elements at a switching frequency lower than the switching frequency at which to switch on and off the first switching elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving device for rotating electric machine","description":"In a driving device for a rotating electric machine, a first inverter unit blocks and allows, for each winding of multi-phase windings of the rotating electric machine, current conduction on one side ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11489474","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.
