Industrial motor drives and controls

The unique and specific requirements of motor drive systems demand a new approach to IGBT design. With the right IGBT technology, it is possible to create better-positioned modules to address these needs. This approach Infineon has taken with its latest generation of IGBT technology, the IGBT7.

At the chip level, the IGBT7 uses micro-pattern trenches (MPT), the structure of which contributes significantly to reducing forward voltage and increased conductivity in the drift zone. For applications with a moderate switching frequency, such as motor drives, the IGBT7 delivers a significant reduction in previous generations' losses. Another improvement offered by IGBT7 from a generation earlier (IGBT4) is the freewheeling diode that has also been optimized for drive applications. The forward voltage drop of the emitter controlled diode, EC7, is now 100 mV lower than the forward voltage drop of the EC4 diode, with improved reverse-recovery softness.  Learn more

With more automation being used across industries, there is a correspondingly increased demand for servo motors. Their ability to combine precise motion control with high torque levels makes them the perfect fit for automation and robotics.

Using its manufacturing expertise and long experience, Infineon has developed a SiC trench technology that offers higher performance than the IGBT but with comparable robustness, e.g., short-circuit time of two (or 2) µs or even three (or 3) µs. Infineon's CoolSiC™ MOSFETs also address potential problems inherent in SiC devices, such as unwanted capacitive turn-on. Furthermore, the SiC MOSFETs are available in the industry-standard TO247-3 package, and now with even better switching performance, in the TO247- 4 package. In addition, the CoolSiC MOSFETs are also available in the SMD package TO267-7. Besides these TO-packages, the SiC MOSFET is also available in Easy 1B, Easy 2B, and 62mm packages.  Learn more

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.

This training will introduce you to how the CoolSiC™ will help to design the next generation of servo drives.

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.

In this 6 min training, we will show the main trends of servo drives, compare CoolSiC™ MOSFETs to IGBTs and explore the 1200 V class CoolSiC™ discrete portfolio.

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.
