Current Source Inverters Advantages

  1. Capable of regeneration back to the a.c. line because of d.c. link polarity can be reversed.
  2. Large d.c. link filter inductor and regulated power supply act as a current limiter, making it easier to apply protective fuses.
  3. Ability to ride through power-link interruptions.
  4. The converter-grade thyristors are sufficient.
  5.  Current source inverters does not generate radiofrequency interference.

Current Source Inverters  Disadvantages

  1. Cogging can occur at speeds below 6 Hz.
  2. D.C. link filter inductor is large, costly, and contributes to losses and enclosure size.
  3. Can cause high voltage spikes on motor terminals.
  4.  Usually not possible to use with more than one motor.
  5. Motor power factor appears on the incoming line to the controllers.
  6. Voltage clamping devices lower overall efficiency.
  7. May require special tuning to motor parameters.
