Galley Power LLC SBIR Phase I Award, May 2018

This Phase I research will model, design, simulate and verify feasibility of a new type of high power density, ultra-low ripple 1kV battery charger for the US Navy applications. The approaches used in this research rely on the latest developments in wide bandgap semiconductors for the cancelling of current ripples and special driving and control methods for SiC devices in order to achieve ultra-high power density and efficiency. The proposed charger concept will optimize space, weight, power and cooling based on the design requirements. The research will provide design specifications for engineering development and also identify key design strategies.
