1, -IGBT: IGBT is an insulated gate bipolar transistor, which combines the characteristics of MOSFETs and bipolar transistors. The IGBT has an insulated gate, PN junction and bipolar transistor structure. It is suitable for medium to high voltage and medium frequency applications.
2, IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is composed of BJT (bipolar transistor) and MOS (insulated gate type field effect tube) composite voltage driven power semiconductorIt combines the advantages of high input impedance of MOSFET and low on-voltage drop of GTR.
3, igbt is: insulated gate bipolar transistor. igbt is the core device of energy conversion and transmission, commonly known as the "CPU" of power electronic devices. As a national strategic emerging industry, it is widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment.
1. Baidu Knows is independently developed and based on search by Baidu, the world's largest Chinese search engineInteractive quiz sharing platform. Users can raise targeted questions according to their own needs; At the same time, these answers will be used as search results to meet the needs of users with the same or similar questions.
2, check browser compatibility: Different browsers have differences in supporting web functions. Try opening Baidu Know in a different browser to see if you can successfully click the avatar option. If you have problems with a particular browser, you can try updating your browser version or try using a different browser.
3, Baidu included the rules are calculated by Baidu search engineIts specific rules and algorithms are Baidu's trade secrets and are not publicly disclosed to outsiders.
4, click my, you can see the entrance. Below I will share with you the method found: the software version of this demonstration: 130. Phone model: vivo y31s. The specific steps are as follows: Open the Baidu app on your phone and click on the lower right corner of [My]. Then you can see [Ask].
5, the difference is as follows: Different nature Baidu Know is a search-based interactive knowledge sharing platform, launched on June 21, 2005It was officially released on November 8, 2005. Baidu Encyclopedia is an open and free online encyclopedia launched by Baidu.
6, simply put, Baidu know is the type of question and answer, Baidu encyclopedia is a more comprehensive introduction, encyclopedia type. "Baidu knows" is a search mode in which users themselves raise questions according to their own targeting, and trigger other users through the point reward mechanism to solve the problem.
PerformanceDifferent, different uses, etc. frd chip and igbt chip difference: performance is different, FRD chip is a chip used in the field of network security, IGBT chip is a power semiconductor device.
Structure difference difference: FRD chip refers to the abbreviation of FreeRecoveryDiode, is a forward recovery diode. Refers to the IGBT chip InsulatedGateBipolarTransistor, is a kind of triode structure of power switch device.
OH is to prevent IGBT, FRD (fast recoveryDiode) overheating protection. There is no temperature detection element on the insulating substrate inside the IPM, and the temperature Tcoh of the insulating substrate is detected (the protection action time of IGBT and FRD chips after abnormal heating is relatively slow).
U-IGBT U (Groove structure) -IGBT is a groove carved on the tube core, and a groove gate is formed inside the chip cell. After using the channel structure, the cell size can be further reduced, the channel resistance can be reduced, the current density can be improved, and the product with the same rated current and the least chip size can be manufactured.
