In some embodiments the amplitude control loop operates at an amplitude that is proportional to an amplitude of an input signal at a fundamental system frequency and at a selected harmonic of a fundamental system frequency; and the frequency control loop operates at a fundamental system frequency and at a selected harmonic of the fundamental system frequency. The frequency control loop may adaptable to a fundamental control system frequency or to a selected harmonic of the fundamental control system frequency. The controller may be implemented as a resonant controller and used in various ac systems, and offers high structural robustness in digital implementations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital controller for a power converter","description":"Provided are methods and circuits for a controller for a control system, comprising first and second control loops that operate substantially independently, wherein the first control loop is an amplit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9698665","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.
