Fraunhofer Institute for Integrated Systems and Device Technology IISBIn many electrical configurations, a DC-DC converter stabilizes or boosts the energy from a battery or fuel cell to the HV-power-net. For Motor Sport applications or prototype vehicles, a robust but very small and light weight power electronic is essential. Within a very short time, the IISB develops and builds up A- and B- style grade prototypes. These are typically controlled by CAN and provide all basic safety and power conversation functions like active discharge, basic- and reinforced isolation, voltage- and current control loops and status feedback.
