工业电机驱动和控制

电机驱动系统独特的需求要求IGBT设计具有新的思路。只有合适的IGBT技术，才能制造出定位更好的模块来满足这些需求。英飞凌则采用了最新一代的IGBT技术IGBT7做为新思路。

在芯片层面，IGBT7使用微模式沟槽技术（MPT），其结构有助于显著降低正向电压和增加漂移区的电导率。对于中等开关频率的应用，如电机驱动，IGBT7可显著降低前几代产品的损耗。另外，与前几代产品（IGBT4）相比，IGBT7还有一个改进是针对驱动应用进行优化了的飞轮二极管。现在，发射极控制二极管EC7的正向电压降比EC4二极管的正向电压降低100毫伏，反向恢复软度有所改善。了解更多

随着自动化程度的提高，对伺服电机的需求也相应增加。他们将精确的运动控制与高扭矩水平相结合的能力使他们非常适合自动化和机器人技术。

英飞凌利用其专业制造知识和长期经验，开发了一种SiC沟槽技术，其性能高于IGBT，且具有不错的稳定性，例如，短路时间为两（或2）µs，甚至三（或3）µs。英飞凌的CoolSiC™ MOSFETs 还解决了碳化硅元器件固有的潜在问题，例如不需要的电容性导通。SiC MOSFETs在工业标准TO247-3封装中可用，现在在TO247-4封装中具有更好的开关性能。此外，CoolSiC MOSFETs也可在贴片封装TO267-7中使用。除了这些TO封装外，SiC MOSFET还提供Easy 1B、Easy 2B和62mm封装。

In this training, we will see how Infineon’s two-level slew-rate control (or 2L-SRC) gate driver IC can help overcome gate resistance dimensioning trade-offs in order to obtain reduced switching losses.

We will also see an example of gate resistor dimensioning, with an under-five V/ns voltage slope target, as usually seen in drive applications.

Tutorial about how to select the reliable and efficent solutions regarding the requirements for industrial drives. We take a look on the key questions of power, voltage, topology and frequency related to your application.

本培训将向您介绍CoolSiC™如何为下一代伺服驱动器设计服务。

Every switch needs a driver, and the right driver makes a difference.
Infineon offers different isoalted gate driver families, such as the EiceDRIVER™ Compact and the EiceDRIVER™ Enhanced. Each family has different features to protect the switch and application.
The EiceDRIVER™ isolated gate driver offers advanced features such as reinforced isolation, Miller clamp, slew rate control and short circuit protection to protect the switch and application. It also enables condition monitoring and rapid prototyping.
The EiceDRIVER™ is the perfect fit for industrial application, particular in combination with Infineon CoolSiC™ and IGBT switches.

Do you know what industrial automation is? Join us on this journey through the world of factory automation and find out how semiconductor solutions help factories become smart!  Modern industries typically require many coordinated single steps to accomplish a finished product or any activity flow. Imagine this with no automation in place: any high volume outputs or uninterrupted courses of action at a high level of quality and in a short time would not be possible, would it?

Servo drives come handy in a lot of applications, but controlling them and the power needed to drive them can be challenging when attempting to do it efficiently. Similarly, handling overload and short-circuit conditions is critical. Through this webinar, we will demonstrate best practices of protecting them and how to ensure the protection is reliable, robust and sufficiently fast for all operations. We will also give an exciting overview of suitable boards for evaluation and show the comprehensive Infineon portfolio of SiC MOSFETs and gate driver solutions.
