The boost converter includes an active switch controlled by a control algorithm that, when renewable power is available, operates the active switch at a duty cycle that allows power to flow from the renewable energy generator to the first DC bus and on to charge the battery (without passing though the primary side AC/DC rectifier) or on to supply the electrical grid (without passing through the DC/AC inverter and secondary side AC/DC rectifier), and, when not available, disables the active switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bidirectional battery charger integrated with renewable energy generation","description":"In one embodiment, a bidirectional battery charger integrated with renewable energy generation includes a primary side AC/DC rectifier coupled to the electrical grid and a first DC bus, a DC/AC invert","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787117","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.
