Multiphase space vector pulse width modulation

open access: yesIEEE Transactions on Energy Conversion, 2002
Pole-phase modulation adjusts the pole-phase ratio of an induction machine and requires a multileg, multiphase inverter. This paper analyzes an n-leg, n-phase inverter, and presents techniques for n-phase space vector pulse width modulation (SVPWM). In particular, nine-phase SVPWM is developed and implemented on a nine winding induction machine.

Space vector modulation method for modular multilevel converters [PDF]

open access: yesIECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper presents a generalized space vector modulation (SVM) method for any modular multilevel converter (MMC). The proposed SVM method produces the maximum level number (i.e., 2«+l, where n is the number of submodules in the upper or lower arm of each phase) of the output phase voltages and a higher equivalent switching frequency than other ...

Performance of BPSK subcarrier intensity modulation free-space optical communications using a log-normal atmospheric turbulence model [PDF]

open access: yes, 2010
In this paper, we present simulation results for the bit error rate (BER) performance and the fading penalty of a BPSK - subcarrier intensity modulation (BPSK-SIM) free-space optical (FSO) communication link in a log-normal atmospheric turbulence model ...

General Theory of Space Vector Modulation for Five-Phase Inverters

open access: yes, 2008
Multiphase motor drives are a very promising technology, especially for medium and high power ranges. As known, a multiphase motor drive cannot be analyzed using the space vector representation in a single d-q plane, but it is necessary to introduce ...
