Bi-directional circuits are critical to effectively smooth the supply / demand variation in renewable energy applications. In the past, they were expensive to make and complex to implement in power electronics applications. Wide bandgap GaN power ICs with integrated drive and advanced circuit functions deliver easy-to-use, reliable, high power density and functionality for power factor correction circuits, solar inverters, and solid state circuit breakers.
