The controller includes an MPPT control unit which follows a maximum power point with a period based on a zero-cross detection signal of a system voltage based on an input signal acquired by subtracting a value obtained by multiplying a droop gain simulating drooping characteristics, a control unit which outputs a direction value in such a manner that a difference between a reference output from the MPPT control unit and the input signal becomes zero, and a PWM comparator which outputs a PWM signal based on the direction value and a triangular wave voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion apparatus","description":"According to one embodiment, an apparatus includes a controller which outputs a signal for controlling ON and OFF of a switch which changes over connection between a second input terminal and the outp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531855","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.
