Compact and efficient power electronics with applications to battery management systems

This work investigates the use of advanced power electronics techniques for a variety of applications to both improve efficiency and decrease the size. The first area of research is on investigating limitations in high density switched-capacitor converters for voltage step-up applications. The results from this could be particularly useful for pulsed power applications. This work uses techniques such as resonance, advanced control, and interleaving in the Dickson converter to avoid common limitations in switched-capacitor circuits. Another area of research is on fast battery charging using active battery management system topologies. These topologies have been proven before but this work expands upon those by using modern power electronics techniques to minimize the size and maximize the efficiency. This is achieved by using high frequency, GaN switches, planar magnetics, and active core resetting in a forward converter. This system was developed to be isolated and bi-directional so multiple active battery management system topologies could be used from the same design.
