描述

1、IGCT具有电流大、阻断电压高、开关频率高、可靠性高、结构紧凑、低导通损耗等特点，而且造成本低，成品率高，有很好的应用前景。
2、相对于IGBT而言，IGCT投放市场的时间较晚，应用也没有IGBT广，技术成熟度不如IGBT。 目前的 IGBT和IGCT开、关损耗都差不多，构成的变频器，效率也差别不大。 要论优势，主要是IGCT的耐压目前比IGBT的耐压高，应用于高压变频器的话使得器件减少。但是目前的风电变流器都是690V的，IGBT的耐压也就足够了。 IGBT和IGCT，谁是电力电子器件的发展方向？目前学术界正在争论，虽然IGCT出现晚，但至少在目前，还看不出它相对IGBT有什么优势。但也有可能随着技术的发展，两者并驾齐驱，或者都被某种新的器件代替。

与IGCT所对应的是IEGT， IEGT也称为压装式IGBT （PPI)。

1. IGCT has the characteristics of high current, high blocking voltage, high switching frequency, high reliability, compact structure, low conduction loss, and low manufacturing cost, high yield, and has good application prospects.
2. Compared to IGBT, IGCT was launched relatively late in the market, and its applications were not as extensive as IGBT, with a lower level of technological maturity. At present, the switching losses of IGBT and IGCT are similar, and the efficiency of the frequency converter is not significantly different. In terms of advantages, the main reason is that the withstand voltage of IGCT is currently higher than that of IGBT, which reduces the number of devices when applied to high-voltage frequency converters. However, the current wind power converters are all 690V, and the withstand voltage of IGBTs is sufficient. Who are the development directions of power electronic devices, IGBT and IGCT? At present, the academic community is debating that although IGCT appeared late, at least for now, it is not clear what advantages it has compared to IGBT. But it is also possible that with the development of technology, the two are on par, or both may be replaced by some new device.
Corresponding to IGCT is IEGT, also known as pressure mounted IGBT (PPI).
