“…This can be attenuated by adding damping resistive elements, but using them also reduces the overall efficiency. Space vector modulation (SVM) has proven to result in a high voltage gain, reduced switching frequency and low *Correspondence: neukirchner.laszlo@uni-pannon.hu current harmonic distortion, and could be straightforwardly implemented in digital systems [1]. In the second section, the structure of the investigated inverter is presented.…”

A current source inverter model has been developed in the given paper that is constructed from six LTI models for the different switching modes. The overall model is in a piecewise affine form that supports the use of model predictive control. The model has been verified against engineering expectations and its open-loop performance shows that it is a promising basis of model predictive control structures.

“…They find application in many key industries like rolling mill drives, large fan drives, pump and compressor drives, elevators (and escalators), conveyer belts, and ship propulsion [1]. Major advantages of CSI drives over VSI drives include built-in power regeneration, inherent short circuit protection and low voltage stress on motor [1][2][3][4][5][6][7].…”

Abstract-A dual gate-turn-off thyristor current-source converter topology with sinusoidal inputs is proposed for high-power applications. The sinusoidal input current is realized by using pulsewidth modulation techniques to eliminate 11th and 13th harmonics and a transformer to cancel 5th, 7th, 17th, and 19th harmonics. Three switching patterns are proposed with a switching frequency of 360 or 420 Hz. The combination of these switching patterns provides a full-range control over the dc output current. Resonant modes of the proposed system are identified, and the criterion for the line capacitor design is provided. Simulation and experimental results are given to verify the theoretical analysis.
