A controller computes the variable pre-drive pulse with the controller, and a sense resistor in series with the power converter inductor detects a zero voltage switching condition point and/or a zero voltage switching condition point. The driver includes a power converter that receives an input voltage vin as input and generates a clean folded waveform as an output. An unfolding stage referenced to vin receives the clean folded waveform from the converter and unfolds the folded waveform into a full waveform."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reducing losses and distortion in a driver with a capacitive load","description":"A method for reducing switching losses and waveform distortion in a driver for a circuit with a capacitive load includes generating a variable pre-drive pulse to achieve zero voltage and zero-current ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11239404","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.
