In the LC filter connected between the direct current power source and an inverter circuit, an N channel MOSFET is arranged between a capacitor and ground. When a BPF detects an occurrence of the resonance in the LC filter, an inverting amplifier operates the N channel MOSFET and changes a series resistance value of a current path on which the capacitor is arranged."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion system","description":"In a power conversion system, when a frequency of a ripple current, flowing into a power supply line of a direct current power source, is equal to a resonance frequency of an LC filter, a resonance is","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762147","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.
