The driving signal transmitting circuit receives a control signal and generates a driving signal according to the control signal to drive the power semiconductor switch module. The failure detecting circuits generate a fault signal when they detect that one of the power semiconductor switches and/or the driving signal transmitting circuit is malfunctioning. The isolated pulse transforming unit of the protection signal transmitting circuit receives a corresponding fault pulse signal generated according to the fault signal, and outputs a protection pulse signal. The control circuit generates the control signal and receives a protection signal generated according to the protection pulse signal. The control circuit generates a turn off signal according to the protection signal to turn off the power semiconductor switch module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device and method for transmitting protection signal using the same","description":"A power conversion device includes a power semiconductor switch module, a driving signal-transmitting circuit, a plurality of failure-detecting circuits, a protection signal transmitting circuit and a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9748831","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.
