The augmented modular multilevel converter
TL;DR: The Controlled Transition Bridge (CTB) as mentioned in this paper is a class of converter topology that combines series connected semiconductor "director valves" with chains of switched capacitor modules, "chainlink circuits", in such a way that the director valves carry the main current for a significant portion of the period and the chainlink circuits provide a controlled traverse of voltage between different director valves conducting.

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.
