In one embodiment, the device includes a capacitance change detector that detects a change of an electrostatic capacitance (impedance) connected to the power system. When the resonance detector detects the resonance, a current command value generator generates the current command value on the basis of harmonic components included in a current supplied from the power apparatus to the power system. When the impedance change detector detects a change of the impedance, the current command value generator generates the current command value so as to reduce the compensating current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resonance suppression device","description":"A resonance suppression device, in which power loss and apparatus capacitance are reduced by outputting a compensating current only while a voltage resonance is being generated, and which suppresses r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9590485","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.
