Description
The reference board REF_10KW_3LBUCK_SIC400 uses a 3-level-flying capacitor Buck DC/DC converter, which can also be reconfigured to be used as a 2-level Buck DC/DC converter. The primary goal of the platform is to enable evaluation of CoolSiC™ MOSFET 400 V and 650 V G2 in TOLL and D2PAK-7 packages. The reference design also aims to provide layout guidelines to optimize the commutation and gate loops and provide solutions for auxiliary supply for floating gate-drive, startup, pre-charging and voltage balancing of the flying capacitor in multi-level topologies. By enabling a fair benchmarking between 3-level (3L) and 2-level (2L) topologies, you can evaluate the following benefits of adopting a 3-level topology: • Lower voltage swing across the inductor (factor 0.5 x) combined with the benefits of “series interleaving”, where the inductor ripple frequency is double that of the MOSFET switching frequency, allows for a significant reduction (factor 0.25 x) in required inductance value. • For a given size, the inductor can be optimized to reduce conduction and core losses for higher efficiency. Alternatively, a smaller inductor can be used to increase power density. • Lower blocking voltage across the MOSFETs enable the use of lower-voltage rated switches with better switching Figures of Merit (FoM) – effectively lowering the switching losses significantly.
