C332 Silicon Carbide Power Electronics & System Integration: The proposed effort is to develop a prototype demonstrator of a SiC-enabled hybrid modular multilevel converter (HMMC-SiC) that is targeted for high power and medium voltage power system applications in particular for ship propulsion and ship integrated power systems. The development will focus on generating key sub-assemblies such as the full-bridge submodules (SMs) with SiC MOSFETs (SMs-SiC) and SMs with silicon IGBTs (SMs-Si) with a focus on SMs-SiC, and the medium voltage IGBT semiconductor switches (MVSS) assemblies. These building block assemblies (SMs and MVSS) include the semiconductors and their peripherals such as gate drivers, power supplies, protection, capacitors etc. Further we will integrate these elements into a working and demonstratable system in commercial or custom packaging with dedicated hardware such as the arm inductors, bus work, controllers etc. This will mature and elevate the technology readiness level (TRL) propose this converter topology for near- and mid-term US Navy ship propulsion and power system applications. CA21 Silicon Carbide Semiconductors: The focus of this project is the design, development, and testing of silicon carbide (SiC) semiconductor devices. The primary objectives are to achieve a reduction in the physical size of the components and an increase in their switching frequency capabilities. This involves leveraging the superior material properties of SiC, such as its higher breakdown voltage and thermal conductivity, which allow for more compact and efficient power electronic systems. The faster switching speeds of SiC transistors lead to smaller passive components, further reducing the total size of the drive/converter. The design and testing process will validate the performance and reliability of these next-generation SiC devices for high-power applications. CA22 Integrated Silicon Carbine Bi-Directional Power Converter: This advanced technology provides wide-bandgap properties which enable power conversion systems with higher power density, allowing for reduced size and weight while delivering higher efficiency.
