Upon activating the driver by an activation pulse, the power capacitor is being charged in a constant current determined by the current limiting resistor, until reaching a desired voltage, while the voltage across the power capacitor follows the volage across the control capacitor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuit for linearly charging power capacitors","description":"A circuit for effectively controlling the process of pre-charging a power capacitor, comprising an integrator circuit consisting of an operational amplifier implementing a voltage dependent current so","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11973367","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.
