The power converter is equipped with a controller and a switching circuit which is disposed between a power supply and windings of the electric rotating machine. The switching circuit has switches grouped into an upper and a lower arm. The controller works to control an off-operation of one of the switches of one of the upper and lower arm so as to produce a desired length of the current flywheel duration following turning off of the one of the switches, thereby minimizing a loss of rectification and avoiding the backflow of current from the power supply to the windings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power converter for electric rotating machine","description":"A power converter for an electric rotating machine is provided which is designed to ensure a desired length of a current flywheel duration in which current is permitted to freewheel from the electric ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8513907","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.
