For example, power switches that control the input power to the voltage converter must use this time delay in order to, e.g., achieve zero-voltage switching (ZVS) with minimal dead-time. The time delays are typically considered as constants, and the power switch control is optimized for a limited operational range that corresponds to such constant time delays. Herein, variable time delays are determined based upon varying load conditions of the voltage converter. By more accurately determining the time delay for a given load condition and basing the voltage converter control on such accurate (load-dependent) time delays, the voltage converter may be more optimally controlled and achieve higher efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Estimation of transformer leakage inductance and associated delay in voltage converters","description":"A time delay through a voltage converter, including a transformer therein, must be known or estimated in order to optimally control the voltage converter.
