Observer-Based Control Of LLC DCDC Resonant Converter Using Extended Describing Functions

Observer-Based Control of LLC DC/DC Resonant Converter Using Extended Describing Functions Abstract: This paper presents theoretical and practical results about dynamic analysis, frequency response, and control of a LLC resonant dc/dc converter operating under wide input voltage and load variations. A nonlinear model for the LLC resonant converter was developed using the extended describing function […]


Accurate Evaluation Of Leakage Inductance In High-Frequency Transformers Using An Improved Frequency-Dependent Expression

Accurate Evaluation of Leakage Inductance in High-Frequency Transformers Using an Improved Frequency-Dependent Expression Abstract Moving toward higher power density in magnetic components, which is often realized by increasing the operating frequency, leads to the need for development of more accurate design tools, for example, more accurate expressions for core losses, winding losses, and leakage inductance […]
