Researchers in the Stanford University Power Electronics Research Lab have designed an easy to implement, high-efficiency, high-frequency power amplifier with low voltage stress.
Researchers at Stanford have developed a method to tune power amplifier circuits to directly connect their output power (and adjust the combined output power) without any additional power combiner network.
This single-stage resonant inverter architecture achieves constant power and efficiency over a large bandwidth, solving one of the largest problems with state-of-the-art resonant inverter power amplifier architectures.
Stanford researchers have designed a high-voltage cascode GaN/SiC device combining the advantages of both a GaN and an SiC device (i.e. reduced gate loss/simple gate drive requirements)
