CoolSiC™ and EiceDRIVER™ - The Perfect Solution for Servo Drives

Controlling servos, managing power requirements and ensuring fail-safe operation can be challenging, especially as efficiency demands increase. Dealing with overload and short-circuit conditions is also a must. In this webinar, we will learn how Infineon's CoolSiC™ MOSFETs support the transition to more efficient servo drives and how EiceDRIVER™ gate drivers ensure proper protection.

As CO2 reduction and increased efficiency become standardized in the industrial, consumer and automotive sectors, smart, electrically controlled and efficient motor drives are phasing out mechanical motor controllers.

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.

The drives market has become more focused on motor integrated drives. This reduces the expensive shielded motor cables and relaxing the switching speed requirements. Alongside the well-established IGBT technologies, Infineon offers SiC MOSFETs, a technology that enables better motor integration of the inverter. This is made possible due to enhanced material properties, which offer lower switching losses and excellent low conduction losses in light load applications.

This webinar shows how Infineon's CoolSiC™ MOSFETs and EiceDRIVER™ gate drivers address these challenges.

Initially we will compare the performance and operation of IGBTs and SiC MOSFETs used in servo drives. Afterwards we will discuss the challenges of driving and protecting SiC MOSFETs and how to address them with the EiceDRIVER™ gate driver. We will examine some of the pitfalls of driving SiC MOSFETs and what solution are there to address them. Lastly, as SiC MOSFETs have reduced short-circuit withstand time capabilities, 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.
