چکیده
This paper presents a novel configuration of separate zigzag transformers based 18-pulse AC –DC converter for improving the ripple factor & isolation of three phase uncontrolled rectifier, this approach eliminates the complexity required to design a complicated auto transformers or isolated multi winding transformer as used with other systems. The paper also presents the comparison among 12 pulse and 6 pulse AC DC converter for different parameters like ripple factor, harmonic distortion in input current for unbalanced supply voltage, efficiency of the converters, power factor variations of input power supply all these parameters are compared for no load light loads & full load conditions we further extend our simulation for measuring the effects of different type of filters like L, C & LC the simulation results shows some useful & interesting results which can be used for developing or selecting the best configuration for practical developers.

متن کاملPower Upgrading of Transmission Line by Injecting DC Power in to AC Line with the help of ZIG-ZAG Transformer
We never loaded a long extra high voltage to their thermal limits in order to keep sufficient margin against transient instability. With this scheme proposed in this paper, it is possible to load these lines very near to their thermal limits. Here we inject dc power in to dc transmission line to carry usual ac along with dc superimposed on it. The added power flow does not cause any transient i...

In this paper, a 24-pulse ac-dc converter is designed, modeled and simulated based on a fork autotransformer to improve power quality indices. The use of autotransformer results in reduced kVA rating of the proposed topology as compared with the transformer based 24-pulse converter. Due to the proper flexibility of the proposed topology, it can be simply utilized in other similar applications. ...
