This paper describes the design and implementation of a compact and high-frequency LLC converter with wide input voltage range (from 220 V to 320 V), output power range (from 250 W to 1.5 kW), high efficiency (over 96 % at full power), high power-density (32 kW/dm 3 ) and narrow frequency variations (15 %)…
This paper exposes the analysis, modeling and comparison of two different LLC converter configurations: the conventional LLC converter and the Three-Phase Y−Δ LLC converter, which is firstly analyzed in this paper…
Aircraft applications are in continuous need to reduce equipment volume to optimize fuel and weight. Power converters are an essential part of this volume since electric distribution has either AC and DC buses…
COTS evaluation – COTS qualification – Design of space converter:
Option 1: 3D stacking,
Option 2 : Open frame,
