How to Measure and Reduce Common Mode EMI in Electric Drive Installations

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.

Rohde & Schwarz and Quectel Cooperate on Cellular-V2X Test Case to Accelerate 3GPP Validation in the Automotive Industry

Cellular-V2X (C-V2X) is a key technology which will improve road safety and accelerate autonomous driving in the coming years. Specifically, the C-V2X PC5 interface, operating in the 5.9 GHz frequency enables direct, reliable, low latency communication between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and pedestrians (V2P). In order for the automotive industry to deploy this technology in a timely manner, cooperation between suppliers in this industry becomes increasingly important.
