Technology Description:

NextWatt is developing an ultrawide-bandgap optical triggered device that addresses the need for fast protection for solid-state transformers (SST), a promising technology for revolutionizing substations and renewable energy systems. NextWatt seeks to build an ultrafast optical switching device using a low-cost beta-gallium oxide semiconductor triggered with a readily available mid-wavelength optical beam. If successful, the device would enable solid-state-circuit breakers for protection of SSTs and other power and energy applications.
