GaN transistors are the future of power electronics because they can quickly transition from on to off at 1-2ns instead of 20-50ns for Si and SiC transistors. Fast switching means that less energy is lost as energy loss occurs when the transistor is neither on nor off. However, above 100 kHz there are issues with overheating and EMI. This talk explains the issues and how QPT has solved them so that GaN is unleashed to switch at up to 20 MHz for ultra-efficient switching. This will accelerate GaN’s use into new application areas worth over $360 billion.
