Wide Band Gap High Current Solid State Circuit Protection Device

The Phase I goal is to demonstrate a baseline 80A rated high efficiency circuit protection device (CPD) module. The scalable power architecture allows for direct concatenation of these units as to attain a range of 80A-640A rated, highly compact/high efficiency power protection units for the Next Generation Combat Vehicle Electrical Power Architecture (NGCVEPA). The advanced design will be available in two versions - normally open (off) and normally closed (on) based on different wide bandgap (WBG) based power components. Although these two versions use distinct WBG components, they will have large commonality, with common advanced and i/o features, control design and implementation. This solid-state circuit protection device will increase ruggedness against typically vehicle shocks and react quicker to shutoff current as compared to a mechanical device. The power range (80A to 640A) afforded by these protection modules will provide a means to program a design I2t trip curve. Phase I Option will exit with testing of a tightly constructed 160A rated circuit protection module hardware demonstration unit for both normally open and normally closed versions.
