【摘要】

：

变压器是交流电压转换必不可少的装置,在降低重量和减小体积上仍有改进的余地,特别是低频变压器,其体积较大.如今,半导体技术的进步使变压器能够在任意频率下工作,其体积变小、重量变轻.上世纪90年代左右,日本采用半导体技术研发的电力电子变压器用作辅助电源装置的隔离型DC-DC变换器,2000年以后欧洲开发了用于主回路的电力电子变压器.介绍几种电力电子变压器,抛砖引玉,以期待未来能够促进这种技术的进一步发展.

Genetically encoded BRET-activated photodynamic therapy for the treatment of deep-seated tumors

Photodynamic therapy (PDT) is one of the most appealing photonic modalities for cancer treatment based on anticancer activity of light-induced photosensitizer-mediated reactive oxygen species (ROS), but a limited depth of light penetration into tissues do

Mechanism of the trivalent lanthanides' persistent luminescence in wide bandgap materials

The trivalent lanthanides have been broadly utilized as emitting centers in persistent luminescence (PersL) materials due to their wide emitting spectral range, which thus attract considerable attention over decades. However, the origin of the trivalent l

Nanoscale mapping of optically inaccessible bound-states-in-the-continuum

Bound-states-in-the-continuum (BIC) is an emerging concept in nanophotonics with potential impact in applications, such as hyperspectral imaging, mirror-less lasing, and nonlinear harmonic generation. As true BIC modes are non-radiative, they cannot be ex

Chip-based multimodal super-resolution microscopy for histological investigations of cryopreserved t

Histology involves the observation of structural features in tissues using a microscope. While diffraction-limited optical microscopes are commonly used in histological investigations, their resolving capabilities are insufficient to visualize details at

Transient measurement of phononic states with covariance-based stochastic spectroscopy

We present a novel approach to transient Raman spectroscopy, which combines stochastic probe pulses and a covariance-based detection to measure stimulated Raman signals in alpha-quartz. A coherent broadband pump is used to simultaneously impulsively excit

Toward implantable devices for angle-sensitive, lens-less, multifluorescent, single-photon lifetime

Implantable image sensors have the potential to revolutionize neuroscience. Due to their small form factor requirements;however, conventional filters and optics cannot be implemented. These limitations obstruct high-resolution imaging of large neural dens

Confined-domain crosslink-enhanced emission effect in carbonized polymer dots

Revealing the photoluminescence (PL) origin and mechanism is a most vital but challenging topic of carbon dots. Herein, confined-domain crosslink-enhanced emission (CEE) effect was first studied by a well-designed model system of carbonized polymer dots (

Hybrid Dirac semimetal-based photodetector with efficient low-energy photon harvesting

Despite the considerable effort, fast and highly sensitive photodetection is not widely available at the low-photon-energy range (～meV) of the electromagnetic spectrum, owing to the challenging light funneling into small active areas with efficient conver
