Analytical Modelling and Optimization of Gapped Core Magnetics in LLC Converter
Lordoğlu, Abdulsamed; Gülbahçe, Mehmet Onur; Kocabaş, Derya Ahmet; Düşmez, Serkan (IEEE, 2021)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 ... -
Efficiency and Power Density Optimization of Three-Level TP PFC
Bulut, Enis Barış; Gülbahçe, Mehmet Onur; Kocabaş, Derya Ahmet; Düşmez, Serkan (IEEE, 2021)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 ... -
Extended Describing Function Modeling and Closed-Loop Control of LLC Converter in Battery Charging Applications
Lordoğlu, Abdülsamet; Gülbahçe, Mehmet Onur; Kocabaş, Derya Ahmet; Düşmez, Serkan (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 ... -

Simplified Method to Analyze Drive Strengths for GaN Power Devices
Bulut, Enis Barış; Gülbahçe, Mehmet Onur; Kocabaş, Derya Ahmet; Düşmez, Serkan (IEEE, 2021)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 ... -
System-Level Design Approach for LLC Converters
Lordoğlu, Abdulsamed; Gülbahçe, Mehmet Onur; Kocabaş, Derya Ahmet; Düşmez, Serkan (IEEE, 2021)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, ...
