Motor Drives
Modern VFDs (Variable Frequency Drives) using IGBT switches for motor
frequency control are prone to much higher EMC being generated because
of high frequency transistor switching. High dV/dt rates at the motor
connected to the VFD result in radiated electric fields and voltage spikes
conducted along the motor cabling.
These emissions can be conducted to other electrical equipment
connected to the utility. EMCS offers solutions for VFD problems ranging
from corrupted data transmission to electric motor drive damage.
