Efficiency and Power Density Optimization of Three-Level TP PFC
Si based three-level (3L) totem-pole (TP) Power Factor Correction (PFC) topology is a low cost alternative to two-level TP PFC with wide-band gap devices providing high power density and high efficiency. This study ...
Simplified Method to Analyze Drive Strengths for GaN Power Devices
GaN power switches enable ultra-fast switching speeds, yet, the maximum gate drive strength is mainly limited by the voltage overshoot across drain-source junction. There is a complex relationship between the power loop ...
Analytical Modelling and Optimization of Gapped Core Magnetics in LLC Converter
LLC converter design remains a challenging task as it is not straight-forward to choose the switching frequency range that can provide ZVS covering application dependent voltage gains, considering the fact that it is a ...
System-Level Design Approach for LLC Converters
LLC resonant converters are designed with a specified resonant frequency that is usually determined based on the experience of the designers while impacting the losses and the dimension of the converter. In this paper, ...
Extended Describing Function Modeling and Closed-Loop Control of LLC Converter in Battery Charging Applications
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
The variable switching frequency control of LLC converters makes the modeling and compensator design rather a difficult task. In this paper, an extended describing function modeling that can represent the beat frequency ...
