Abstract

The principle and the results of an experimental study concerning a new high-power and high-performance inverter drive system will be presented. One usual method of supplying large vector-controlled a.c. drives rated at more than several thousands kW is to combine the outputs of the two inverters using inter-phase reactors. But inter-phase reactors have problems of acoustic noise and high losses, and in addition, are bulky and expensive. Therefore, the new proposal we present offers a new approach to the solution of the above-mentioned problems.
In this paper, the principle of the γ-δ decoupling current controller using matrix theory, the experimental setup of the system, the software of the DSP, and experimental results will be explained. The experimental results show a completely γ-δ decoupling current control of the primary and the secondary magnetizing and torque currents.
