半导体科研项目有哪些

有博方嘉芯氮化镓射频及功率器件项目，中微科技化合物半导体材料研究中心落户成都邛崃，华通芯电第三代化合物半导体项目，三安光电拟160亿在长沙投资化合物半导体项目，江苏任奇芯片制造、封测、研发的产业化基地，郑州航空港实验区第三代化合物半导体SiC生产线，中科院半导体所氮化镓材料与器件项目。

有一些材料的导电性能介于导体和绝缘体之间，常常被成为半导体。半导体是易受温度光照，杂质等因素的影响，半导体是制造电子元件的重要材料，二极管，三极管都是半导体制成的。

Characteristics of modern power electronics laboratory bench:

(1) The experimental apparatus hanging structure, can be freely combined according to the different experimental content, so the structure is compact, easy to use, full-featured, good overall performance, power electronics technology in a device, semiconductor converter technology "courses offered experimental project.

(2) the experimental device small footprint, the conservation laboratory space, no need to set the power control panel, cable trenches, concrete barrier, may reduce investment in infrastructureexperimental device only three-phase four-wire power can be put into use, the laboratory the construction period is short and quick.

(3) The device layout is reasonable, beautiful shape, clear panel diagram, clear and intuitive. Experimental cable using a strong, the weak separate the pistol plug the two not INTERFIX avoid strong electrical access the weak electrical equipment, causing equipment damageexperimental line connection is safe, reliable, quick and easyaddition to the power control panel, pendant also provided laboratory tables can be placed on the desktop oscilloscope experimental apparatus, comfortable, convenient operation. The bottom of the bench mounted wheels and stainless steel mounting adjustment mechanism to facilitate the mobile and fixed.

(4) control panel power supply three-phase isolation transformer isolated, with voltage leakage protection device and current leakage protection device, effectively protect the personal safety of the experimental operation, and to create the security conditions for the open laboratory.

(5) pendant panel is divided into three wiring holes, strong power, weak and waveform observation wells, three obvious difference.

(6) experimental line select typical line, fully compatible with the teaching content, and to meet the curriculum requirements

Maintenance and repair of power electronics laboratory bench:

School power electronics laboratory bench often students use, easy to damage, bench maintenance and repair is a very important thing. Maintenance process involves a very wide range of power electronics expertise and skills, including the detection of power electronic devices, circuit analysis, fault analysis and resolution professional knowledge and skills
