Coupled inductors combined with multilevel and multiphase converters reduce ripple and help with intrinsic flying capacitor voltage balancing. Voltage balancing is important for reducing current ripple and increasing converter efficiency. The capacitor voltage levels are experimentally measured and compared against theoretical models. The results will be used to develop closed-loop control of the converter to track envelope signals with high linearity.application/pdfenPrinceton University Senior Theses
