A Current Source Inverter With Advanced External Circuit and Control Method

  title={A Current Source Inverter With Advanced External Circuit and Control Method},
  author={Sangshin Kwak and H. A. Toliyat},
  journal={IEEE Transactions on Industry Applications},
A thyristor-based current-source inverter (CSI) is proposed, employing a standalone voltage-source inverter (VSI) with a small power rating. The VSI, as an external circuit of the CSI, performs three tasks: 1) turning off of thyristors; 2) transfer of reactive load energy; and 3) clamping peak voltages across the load and thyristors. In comparison with conventional thyristor-based CSIs requiring large ac commutation capacitors as well as individual energy recovery and voltage clamping circuits… CONTINUE READING
