| Abstract |
This paper presents the investigations on the minimization
of the dc link capacitance in ac-dc-ac converters for
induction motor (IM) drives. The minimization is achieved by
fast input-output power control. Furthermore, a major focus of
this paper is the deviations of the system models from the real
system and its effect on predictive output power estimation. The
impact of estimation errors, parameter mismatches and input
saturation on the dc link voltage step response were investigated.
Simulation results are verified by experimental results obtained
from a 15kVA induction motor drive with a dc link capacitance
of only 80ìF. |
