   Bidirectional ZETA-SEPIC Converter as Battery Charging System with High Transfer Ratio
By Alfons KLOENNE [View]
[Download]

Abstract: This paper shows that the ZETA-SEPIC converter can be used as a bidirectional charging system between a high DC link voltage and a low voltage battery system. Main advantages are transformerless operation and that the coupling capacitor protects and separates both sides of the converter in case of short circuits.

   Compact 80 kW Silicon Carbide High Voltage Generator
By Ulf MÜTER [View]
[Download]

Abstract: This paper presents a concept for a compact high voltage generator based on a highly integrated powerchain switching at frequencies above 500 kHz. The high frequency operation in combination with thehigh integration approach enable a reduction of volume and weight of HV-generators used in industrialor medical applications.

   DC-Link Voltage Control Strategy for an NPC voltage source converters in an Effective Energy Storage System
By Arkadiusz KASZEWSKI [View]
[Download]

Abstract: The paper discusses an issue of the voltage balancing in the intermediate DC circuit of a three-level converter system for a smart grid application. A combination of two methods of the voltage balancing is presented in the paper. The voltages of DC-link capacitors, depending on the operating mode, are controlled by the three-level grid connected AC/DC converter or by the two level DC/DC converter and additional balancer circuit. In order to verify the proposed method for the DC-link voltage control, a simulation and an experimental studies have been executed.

   High frequency Soft Switching Half Bridge Series-Resonant DC-DC Converter Utilizing Gallium Nitride FETs
By Yasser NOUR [View]
[Download]

Abstract: The need for Efficient, smaller, lighter and cheaper power supply units drive the investigation of using high switching frequency soft switching resonant converters. This work presents an 88\% efficient 48V nominal input converter switching at 6 MHz and output power of 21 Watts achieving power density of 7 W/cm3. The switching frequency is used to control the output current delivered to the load resistance. The converter was tested using a constant resistance load. The performance and thermal behavior were investigated and reported in this work.
