Researchers in the Stanford University Power Electronics Research Lab developed an effective ring electrode that removes spurious modes in piezoelectric resonators.
Researchers at Stanford have developed a frequency-selective MHz power amplifier for generating dielectric barrier discharge (DBD) plasma. Commercial applications include plasma-assisted nitrogen fixation for fertilizer production.
Researchers at Stanford have developed the first known fixed-frequency control method to enable piezoelectric based power converters to avoid spurious mode and operate across a full output power range while maintaining high efficiency.
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)
Stanford researchers have optimized air-core coil design for wireless power transfer and demonstrated a 2x improvement over current designs. Existing resonant tank and coils are restraining MHz frequency inductive wireless power transfer efficiency.
Engineers from Stanford and the Australian National University have developed a robust micro electric propulsion system to maneuver miniature satellites (CubeSats) and thereby extend their lifetime.
Researchers in Dr. Juan Rivas-Davila's lab have developed 3D printing methods to make aircore inductors and capacitors with more complex geometries and functionality than components using printed circuit boards.
