This paper presents a new multilevel converter topology suitable for very high voltage applications, especially network interties in power generation and transmission. The fundamental concept and the applied control scheme is introduced. Simulation results of a 36 MW-network intertie illustrate the efficient operating characteristics. A suitable structure of the converter-control is proposed.read more

Sine-triangle versus space-vector modulation for three-level PWM voltage-source inverters
TL;DR: In this paper, the inherent relations between sine-triangle and space-vector pulsewidth modulation schemes for three-level voltage-source inverters were studied and it was shown that the two schemes can function equivalently through proper selection of common-mode injections in the case of sine triangle modulation, or dwell times in equivalent redundant switching states in a space vector modulation scheme.
