01. CSI is more reliable than VSI because

  • Two devices in the same leg can conduct
  • It has inherent protection against a short circuit across motor terminals

02. CSI drive has higher cost, weight, and volume
03. Lower speed range and slower dynamic response
04. Not suitable for multi-motor drives
