A peak value of current flowing in the actuation path at the end of an “on” phase is compared with a peak value of current flowing in the recirculation path at the start of the “off” phase in order to detect any malfunction of the circuit. An embodiment of the invention has the advantage of being able to detect any malfunction at very low and very high PWM duty cycles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inductive load control circuit, a braking system for a vehicle and a method of measuring current in an inductive load control circuit","description":"A method and circuit for controlling current through an inductive load such as an electromagnetic valve of a vehicle anti-lock braking system includes first and second driver stages, controlled by PWM","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9673704","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.
