10:00 Optimisation of an Integrated Bidirectional Interleaved Single-Phase Power Factor Corrector
Dipl.-Ing. Johan Le Lesle, Mitsubishi Electric R&D, Rennes Cedex 7, Frankreich
This paper presents a design methodology for a full-bridge interleaved Power Factor Corrector (PFC) converter. The objective of this work is to design a highly integrated converter.This work highlights the fact that is possible to achieve Zero Voltage Switching (ZVS) with high inductor current ripple operation. Moreover interleaving technique permits to reduce EMI filter size. Hence, combining both techniques leads to the design of a high efficiency and high power density converter.
10:25 Multi-MHz LED Drivers: Design for Lifetime and Reliability
Dr.-Ing. Riccardo Pittini, Nordic Power Converters aps, Herlev, Dänemark
LED power supply lifetime is often the limiting factor for LED luminaries. This paper presents the design of a 60W electrolytic-free commercial outdoor LED driver operating at multi-MHz switching frequencies which allow minimizing passive components. Lifetime and reliability predictions based on both mathematical models and manufacturer data are integrated into the design process in order to achieve a lifetime above 130000 hours. Results highlight how high switching frequencies can help to increase the power supply lifespan and reliability.
10:50 High-Frequency and High-Density Design of all GaN Power Supply Unit
Dr. Ruiyang Yu, University of Texas at Austin, Austin, USA
This paper presents the design of high frequency high efficiency all GaN FETs solution for 240Vac to 48Vdc 3.2kW power supply unit (PSU).
11:15 Comparison Between an Interleaved Boost Converter Using Si MOSFETs Versus eGaN HEMTs
Ing. Simon Ravyts, KULeuven, Leuven-Heverlee, Belgien
The paper compares a three leg interleaved Boost converter based of 300 W for a BIPV application. One prototype uses regular Si components, the other prototype is built using wide-bandgap components. Evaluation will be based on efficiency, compactness and thermal behaviour.
11:40 A Novel AC Direct Linear LED Driver with Unity Power Factor, Low Input Current THD, Low Light Flicker and Low Profile
M.Eng. Jie Fu, Philips Lighting, Shanghai, China
A novel low light flikcer and low profile LED driver with unity power factor, low input current THD is proposed in this paper for AC direct lighting. Finally, simulations and prototype experiments verified the proposed LED driver.
