| Abstract |
This paper presents a modulation strategy that enables to copy directly modulated waveform onto
output voltages of a three-phase N.P.C. inverter. A particular modeling of this converter is presented.
The feasibility of a space vector scheme without using a Park transform is studied. All voltage vectors
are drawn into the line to line voltage frame. Then three voltage vectors are selected for the
modulation and simultaneously their durations are calculated. The effect of the modulation on the
capacitor divider is studied and a balancing strategy is deduced. |
