产品参数：ABB 5SHY5045LO020 IGCT系列  晶体半导体模块

  1997年由ABB公司提出。IGCT使变流装置在功率、可靠性、开关速度、效率、成本、量和体积等方面都取得了巨大进展，给电力电子成衰装置带来了新的飞跃。IGCT是将GTo芯

与反并联二极管和门极驱动电

路集成在一起，再与其门极驱动器在外围以低电感方式连接结合了晶体管的稳定关断能力和晶闸管低通态损耗的优点，在导通阶段发挥晶闸管的性能，关断阶段呈现晶体管的特性

IGCT具有电流大、阻断电压高、开关频率、可靠性高、结构点凑、低导通损耗等特点，而且造成本低，成品率高有很好守的应用前景。己用于电力系统电网装置(10MNVA)和的中功率业驱动装置(5MWIccT在中压变频器领城内成功的应用了11年的时间到09年为止),由于IGCT的高速开关能力无需缓冲电路，因而所需的功率元件数目更少运行的可靠性大大增高。(GCT集NG5T(绝湖门[1极双极性晶体管的高速开关特性和GTO(门极关断品何管)的高阻断电压和低导通损耗特性于一体，一般触发信号通过光纤传输到GCT单元。在ACS600的有缘整流单元的相模块里，每相模块由IGCT和二极管

钳位电容组成，由独立的门极

供电单元GUSP为其提供能源。

Product parameters: ABB 5SHY5045LO020 IGCT series crystal semiconductor module

It was proposed by ABB in 1997. IGCT has made great progress in power, reliability, switching speed, efficiency, cost, volume and so on, and has brought a new leap to power electronic fail-out devices. IGCT is the GTo core

With the reverse parallel diode and gate drive electricity

The circuit is integrated together, and then connected with the gate driver in a low inductance mode at the periphery, combining the stable turn-off ability of the transistor and the advantages of the low on-state loss of the thyristor, giving full play to the performance of the thyristor in the on-stage, and showing the characteristics of the transistor in the off stage

IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, structural point and low on-loss, and has a good application prospect of low cost and high yield. It has been used in power system power grid devices (10MNVA) and medium power industry drive devices (5MWIccT has been successfully applied in the medium voltage frequency converter for 11 years to 2009), because the high-speed switching capability of IGCT does not need buffer circuits, so the required number of power components is less and the reliability of operation is greatly increased. (GCT combines the high-speed switching characteristics of the NG5T(absolute lake gate [1-pole bipolar transistor) with the high blocking voltage and low on-loss characteristics of the GTO(gate shutdown device). The trigger signal is generally transmitted to the GCT unit through optical fibers. In the phase module of the ACS600 marginal rectifier unit, each phase module consists of an IGCT and a diode

The clamp capacitor consists of an independent gate pole

The power supply unit GUSP provides energy for it.
