Battery integration: Power converters for future battery technologies

Development of DC-DC power converters specifically dedicated to battery interfacing, with ultra-high efficiency, high power density, and high availability. In collaboration with our partners, we also investigate new charging cycles.

Based on our long-standing expertise in the design and test of isolated and non-isolated DCDC power converters using IGBTs and wide-bandgap devices (SiC & GaN), and conventional as well as high power planar transformers up to several tens of kW.

The Challenge

Many applications such as e-mobility and non-dispatchable renewable sources require fast and high capacity energy storage systems (ESS). In particular, e-mobility application have wide input power bandwidth whereas high density ESS such as fuel-cells are quite slow. Multi-source integration, combining for instance fuel-cells, batteries and super-capacitors can answer these needs. To this end we develop multiport power converters, associated to smart energy management strategies.
