Bidirectional current controller for combination of different energy systems in HEV/EV

High energy traction batteries for plug-in-hybrid-electric-vehicles can deliver an extended driving range, but are limited in power. In contrast, high power systems are limited in energy content.

Description
Summary:	High energy traction batteries for plug-in-hybrid-electric-vehicles can deliver an extended driving range, but are limited in power. In contrast, high power systems are limited in energy content. The combination of high energy and high power systems can solve this problem but will be usually realized through a cost intensive DC-DC converter. This paper presents a low cost yet powerful solution to drive hybrid vehicles with increased pure electric range. This is realized through a variable frequency current controller combining high-energy and high- power-sources. The presented controller shows efficiencies higher 98%. (5 pages)
