The polarity steering switches convey the converter output current to output terminals that connect to a load with a capacitor connected in parallel. A differential receiver is connected to the output terminals to provide negative feedback. A mixer receives an input voltage signal, an output of the differential receiver, and output from a triangle wave generator. A set of two comparators for buck amplifier conversion, or four comparators for buck-boost amplifier conversion, each receives an output of the mixer. Each of the comparators produces a respective output for driving the converter switches through simple steering logic interfaces between the comparators, the converter components and a polarity steering output stage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching audio amplifier","description":"An AC capable power amplifier arrangement is realized that includes a buck converter with a power inductor, two buck switches, and alternately a buck-boost converter using four switches, each driving ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505453","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.
