Offering flexible products for both discrete and coordinated multi-axis drive applications, Siemens employs a common DC bus scenario that offers many advantages.

Some of the Advantages of Common DC Bus

  • Optimize the benefit of regenerative energy

  • Reduce or simplify the type of rectifier needed

  • Reduce power cabling and installation time

  • Reduce footprint of drive line-up

  • Maximize the drive line-up tolerance to incoming line dips/sags

  • Simplify the number of AC/AC points to aid harmonic filtering
