April 5, 2024 — STMicroelectronics recently introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, […]
Researchers developed a 3D full-color display method that uses a smartphone screen, rather than a laser, to create holographic images. Shown are their experimental results, in which a continuous transition from the first layer to the second layer is observable.
