In one embodiment, the method includes monitoring, via a control system, a current-voltage parameter of the power converter, wherein the current-voltage parameter is indicative of an adverse voltage event occurring at the power grid. Another step includes transferring, via a switching power supply, energy from a DC link of the power converter to one or more energy storage devices of an energy storage system coupled to the power converter when the current-voltage parameter indicates that an adverse voltage event is occurring."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for protecting a power converter during an adverse voltage event","description":"The present disclosure is directed to a system and method for protecting a power converter of a renewable energy power system and/or a stand-alone energy storage system connected to a power grid durin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667057","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.
