A bachelor-student project: Buck-boost operation of an integrated H-bridge for variable-speed energy storage systems using measurement coils in the stator of a DC-machine

This paper discusses an interdisciplinary project to be performed by 3^th year bachelor student groups during their last semester. The topic is related to the energy storage in micro dc-grids supplying several electrical drives. The energy storage in the dc-grid is based on the kinetic energy in variable-speed flywheels or in masses performing a linear acceleration-deceleration motion. Such devices have been designed and used at high power already such as in F1-vehicles and public transportation systems. For students, low-power components are more suitable to achieve a self-built setup. One of the challenges in this student project is the low budget of 50 Euro per student pushing them to reuse components found in broken devices or even scrap yards, to look for integrated components or to build low-budget sensors themselves.
