Infineon’s CoolSiC™: The Perfect Solution for Servo Drives

Control, power management and efficiency are common problems with servo drives. Register to learn how Infineon’s CoolSiC™ MOSFETs addresses these challenges.

Since CO2 reduction has become a very high priority in the industrial, consumer, and automotive fields, smart, electrically controlled motors are replacing mechanical motor drives. In the drives market, we see a clear trend towards inverter integration to the motor. This reduces the need for expensive shielded motor cables and relaxes the requirement for moderate switching speeds.

Servo drives are handy for many embedded applications, but controlling them and managing the power needed to drive them can be challenging, especially if one wants to do it efficiently. Likewise, handling overload and short circuit conditions is a requirement.

This webinar shows how Infineon's CoolSiC™ MOSFETs address these challenges. In particular, the presenters use case studies to compare the performance and operation of IGBTs and MOSFETs as used in servo drives.

Attendees will also discover Infineon's .XT interconnection technology for discrete devices. We will look at how .XT interconnection technology enhances thermal and cycling capabilities in a small package form factor.
