| Abstract |
The middle point voltage of the input DC voltages
of the five-level NPC voltage source inverter presents serious
problems caused by a fluctuation of the DC voltage sources
Uc1, Uc2, Uc3, Uc4. As consequence to these problems, we
obtain an output voltage inverter which is asymmetric and
with average value different from zero. In this paper , we will
present one solution to minimize this fluctuation. This
solution uses two two-level voltage PWM rectifiers to supply
the five-level NPC voltage source inverter with clamping
bridge. As application of this cascade, we study the
performances of the three phases induction machine fed by
this association. This drive system can find applications in
great power and high voltage fields as electrical traction. |
