Abstract
This manuscript presents modified scheme of
synchronous space-vector modulation allowing providing
nonlinear dependences between the fundamental voltage and
fundamental frequency of dual three-phase open-winding ac
drive with four modulated inverters. Behavior of the system
with six control modes (characterized by different dc-voltages
and switching frequencies of inverters) and two nonlinear
Voltage/Frequency ratios has been analyzed and simulated by
the means of MATLAB-software.
