LTCC magnetic components for high density power converter

Thick-Film and LTCC Passive Components for High-Temperature Electronics

At this very moment an increasing interest in the field of high-temperature electronics is observed. This is a result of development in the area of wide-band semiconductors’ engineering but this also generates needs for passives with appropriate characteristics. This paper presents fabrication as well as electrical and stability properties of passive components (resistors, capacitors, inductors...

Design proposal for high-efficiency, high-power density dual interleaved LLC converter with interactive control interface

Dual interleaved LLC resonant converter with half bridge topology of main circuit characterized by high switching frequency, high power density and high efficiency over entire operational range is initially described. Consequently, the proposal for a computer control is given. Given type of control approach has been developed for the laboratory testing of resonant converters. The control system...

Thermal Power Density Barriers of Converter Systems

With the desire to integrate power converters into larger systems, high power density became a very important issue. In this paper we discuss the thermal limits of the power density of converter systems. It is shown that these limits are partly given by today’s technology and partly given by physics. Employing the given equations, one can quickly estimate the maximum possible power density of a...

Analysis and Design for a High Power Density Three-Phase AC Converter Using SiC Devices

The development of a high-power-density three-phase ac converter has been a hot topic in power electronics due to the increasing need in applications like electric vehicles, aircraft and aerospace, where light weight and/or a low volume is usually a must. There are many challenges due to the complicated relationships in a three-phase power converter system. In addition, with the emerging SiC de...
