Towards Ultra-High Efficiency Laser Power Converters: 3C- SiC-Based Vertical Epitaxial Hetero-Structure Architecture Devices

We explore 3C-SiC based laser power converters (LPCs) aimed for ultra-high efficiency applications, using the VEHSA architecture. We present 2, 3 and 4 cells VEHSAs optimized at several input power densities (Pin), and we compare them with a horizontal conventional cell (hLPC). VEHSAs obtained larger efficiencies than the hLPC, showing less deterioration with Pin as the number of cells increases.
