The first transistor switch is turned on. The second transistor switch and the fourth transistor switch are turned off. The energy providing circuit charges the parasitic capacitance of the second transistor switch. When the third transistor switch is turned on, the parasitic capacitance discharges the output capacitor to establish the same voltage drops across the parasitic capacitance and the output capacitor. After establishing the same voltage drops across the parasitic capacitance and the output capacitor, the parasitic capacitance of the second transistor switch charges the parasitic capacitance of the fourth transistor switch, thereby establishing a zero voltage drop across the fourth transistor switch and achieving zero voltage switching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direct-current (DC) voltage conversion device","description":"A direct-current (DC) voltage conversion device includes an energy providing circuit, a first transistor switch, a second transistor switch, a third transistor switch, a fourth transistor switch, and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11502606","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.
