Tiny Power Box - Exploiting Multiport Series Resonant Topologies for Very High Power Density Onboard Chargers

Publikation: Konferenzband/Beitrag in Buch/BerichtKonferenzartikelBegutachtung


Growing expectations of modern onboard chargers for bidirectional power, galvanic isolation and additional
low voltage output(s) leads to ever-increasing part count and complexity. Nevertheless, this paper shows
that very high power density can still be achieved with a multiport series resonant topology. Close to
4 kW/dm3 (excl. housing) is achieved for 7 kW and 11 kW applications with a charging efficiency >97%
while meeting most safety and EMI standards resulting in up to 3.1 kW/dm3 (incl. housing) when liquid
cooling is used. An overview of the proposed topology and optimization approach is given followed by a
description of both prototypes with comparison to state of the art.
