A Novel Low Common-Mode Voltage Modulation Strategy for ANPC-5L Inverter [PDF]
In order to suppress the leakage current of the active neutral point clamed five-level (ANPC-5L) inverter, this paper proposes a novel low common-mode voltage (CMV) modulation strategy based on the space vector modulation thought.

Capacitor voltage imbalance is a significant problem for three-level inverters. Due to the mid-point modulation of these inverter topologies, the neutral point potential moves up or down depending on the neutral point current direction creating ...

Online adaptive space vector modulation
In this paper, we present a new modulation method for multilevel three-phase inverters, called online adaptive space vector modulation (oaSVM). The task of a modulator is to reconstruct the desired voltage Ï…* from the available discrete voltage vectors that correspond to the inverter switch positions.

Differential space-time modulation schemes for smart antenna aided generalized multicarrier DS-CDMA systems [PDF]
—Differential space-time modulation (DSTM) schemes were proposed for detection without any knowledge of the Channel State Information (CSI), which is an attractive feature in the presence of fast fading channels, where accurate channel estimation is a ...
