The transformers T* are autotransformers including a core 33* and windings 31* and 32* coupled with each other via the core 33*. One ends of the windings are connected to output terminals of the PWM control bridges 20*1 and 20*2, respectively, while the other terminals are connected to the reactors Ls*. The windings 31* and 32* are wound in such directions that magnetic fluxes generated in the core 33* are cancelled with each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AC power supply device","description":"AC power supply device 1 includes input capacitors 11 and 12 connected at a neutral point X of a three-phase output, transistor bridges 20* (where * denotes U, V, and/or W) each consisting of PWM cont","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11245342","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.
