The protection circuit includes: a constant-current circuit that defines a constant current for drawing a gate charge of the power switching element; a protection switch that controls electrical connection between the constant-current circuit and the gate of the power switching element; and a collector current detector. The collector current detector turns off the on-side circuit to disconnect the power switching element from the main power supply, and turns on the protection switch after a predetermined time has elapsed from when the current value of the collector current of the power switching element exceeds a first threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drive device","description":"A drive device includes: an on-side circuit turning on a power switching element; an off-side circuit turning off the power switching element; and a protection circuit controlling a gate current of th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660636","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.
