The application of IGCT results in the minimum number of power components used in the entire system,and the inherent low complexity of IGCT makes ACS 1000i a drive product with higher efficiency and higher reliability.

The ACS 1000i adopts a three-level inverter,and the power semiconductors do not need a single-tube form in series or parallel.It is the topology with the lowest complexity,the best robustness and the highest efficiency in the field of medium-voltage AC drives today.

The ACS 1000i has a fuseless design.Fuses are known to have low reliability,high cost and are prone to aging.

The ACS 1000i uses advanced,environmentally friendly and oil immersed metal foil capacitors,which have a very long service life compared to the shorter service life of electrolytic capacitors.

IGCT eliminates the need for snubber loops such as capacitors and resistors.The number of components and their losses are thus further reduced.

IGCT的应用致使整个系统使用的功率元器件数量最少，并且IGCT具备固有的低复杂度特性，使得ACS 1000i成为具有更高效率和更高可靠性的传动产品。

ACS 1000i采用三电平逆变器，功率半导体无需串联或并联的单管形式，是当今中压交流传动领域中复杂度最低、鲁棒性最优和效率最高的拓扑结构。

ACS 1000i采用无熔断器设计。众所周知，熔断器的可靠性低、成本高并且易于老化。

ACS 1000i采用先进的、环保的和油浸式金属箔材电容器，与电解电容器较短的使用寿命相比，具有非常长的使用寿命。

IGCT无需缓冲回路，如电容器和电阻器。因而进一步减少了元器件的数量及其损耗。
