IGBT(Insulated Gate Bipolar Transistor),绝缘栅双极型晶体管,是由BJT(双极型三极管)和MOS(绝缘栅型场效应管)组成的复合全控型电压驱动式功率半导体器件, 兼有MOSFET的高输入阻抗和GTR的低导通压降两方面的优点。GTR饱和压降低,载流密度大,但驱动电流较大;MOSFET驱动功率很小,开关速度快,但导通压降大,载流密度小。IGBT综合了以上两种器件的优点,驱动功率小而饱和压降低。非常适合应用于直流电压为600V及以上的变流系统如交流电机、变频器、开关电源、照明电路、牵引传动等领域。IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a BJT (bipolar transistor) and MOS (insulated gate FET) composite full-controlled voltage-driven power semiconductor devices, both MOSFET GTR high input impedance and low conduction voltage drop of both worlds. GTR saturated pressure drop, the carrier density, but the drive current is larger; MOSFET drive power is small, fast switching speed, but the conduction voltage drop large carrier density. IGBT combines the advantages of these two devices, drive power is small and saturated pressure drop. Very suitable for DC voltage of 600V and above converter systems such as AC motor, inverter, switching power supply, electric lighting

Bi-directional SCR can be regarded as a general anti-parallel connected SCR's integration with the general principle of the same one-way thyristor. Figure 1 The basic structure of a two-way thyristor and its equivalent circuit, it has two main electrodes T1 and T2, a gate G, the device gate electrode in the main direction can trigger both positive and negative conduction, Therefore, two-way thyristor in the first quadrant 1 and 3 have symmetrical volt-ampere characteristics. TRIAC gate plus positive and negative trigger pulse can trigger the conduction tube so that, it means there are four types of trigger.

标题翻译如下CCD image sensor and their application study。内容翻译如下Promptness accompanying semiconductor and the photoelectricity technology develops , the solid state image sensor also arises at the historic moment , the productive technology technology can't develop swift and violent. The solid state image sensor is compared with average image sensor , have volume lacking fidelity for a short time, for a short time, sensitiveness is high , resist to vibrate , is able to bear moistness , a lot of merit of cost low grade, therefore can broad apply to industry measurement, is that meticulous of our country processes , development of robot technology and industrial automation field gets the significant effect under the control of, especially waiting for a field in pattern recognition, and with the branch who seeps through each that the industry and agriculture in our country produces broadly. At the same time, computer soft hardware technology never-ending changes and improvements, application that can give a solid state image a sensor also brings about vast vistas. The principle the main body of a book is complied with analysing the solid state image sensor starts off , emphasizes analysis and investigation and discussion being in progress to it in test control and the pattern recognition field.文章有些长、、望认真看完、、标准人工翻译、、希望可以帮助你、、
