| Abstract |
A step-up transformer is being used in frequency
converter motor drives to increase the output voltage of the
supply system. In addition, a larger current requirement is
ensured with parallel frequency converters coupled via threephase
multi-primary step-up transformer. Parallel operation of
inverters with transformer coupling is a difficult task to
implement. In this paper, the whole system and most of the
known problems are introduced. The paper is written on a basis
of literature research, and in the future papers, the solutions for
each problem are presented by means of simulations and
measurements. |
