A plurality of individual controllers are provided respectively corresponding to a plurality of converter cells and generate a gate control signal for controlling turning on and off of a switching element of the corresponding converter cell, based on the first voltage command value and the second voltage command value. When generating the gate control signal using pulse width modulation, each individual controller modulates a carrier signal in accordance with the second voltage command value such that the pulse width of the gate control signal changes in accordance with the second voltage command value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device","description":"In an MMC-based power conversion device, a control device generates, for each leg circuit, a first voltage command value not based on circulating current circulating between a plurality of leg circuit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11936306","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.
