There are numerous mass volume power applications where it is necessary to control the flow of bidirectional power, including electric vehicles (vehicle to grid, vehicle to home, and vehicle to vehicle), distributed and grid-tie power systems using regenerated energy and/or energy storage systems, datacenter grid services with bidirectional UPS and large-scale battery storage, and solid-state circuit breaker protection. Gallium nitride (GaN) bidirectional power switches can enable these applications with their compelling advantages of high efficiency at high frequency operation, which allows for high power density that lowers system weight and volume, and high blocking voltage and temperature capabilities.
