Abstract :
A drive system featuring three-level inverter (also known as neutral-point-clamped inverter) and offering novel features is introduced. The circuit concept not only makes it possible to expand the power range without connecting GTOs directly in series or parallel, but also greatly improves the voltage and current waveforms, enhances control properties and reduces losses. This drive system also features a self-commutated GTO converter on the line side. It permits free energy exchange in both directions without reactive power and with a low harmonic content of the line current.<>
