Abstract
DC-link dynamic is one of the most important issues for current source converters (CSC). In practice, the dc-link voltage suffers from the slow dynamic due to grid disturbances, which will affect the quality of output waveform and damage the converter. Many solutions have been presented to cope with it, but none of them achieve the zero dynamic dc-link voltage control. In order to fill the technical gap, a novel solution is proposed in this paper. Firstly, the impactof grid disturbances on the current source converter (CSC)is discussed with instantaneous power theory and small signal model analysis. Secondly,a new solution is presented to eliminate the adverse impacts of grid disturbances, so as to achieve the zero dynamic dc-link control concept. Meanwhile, the power quality of grid current is improved. Finally, the experiments for the proposed solution under grid disturbances are carried out with TMS320F28335DSP + XC3400FPGA digital control hardware platform. The experimental results verify the effectiveness of the proposed solution.
The dataset contains two files, which are the code of experiment and the video of experiment. The file of the code of experiment contains two files, which are DSP code and FPGA code. These two codes are used in a TMS320F28335 DSP plus XC3S400 FPGA digital platform. Then, combined the digital platform and main circuit of current source converter, the proposed solution and conventional solution can be finished. The file of the video of experiment contains two videos, which are the balanced grid drop video for proposed solution and the unbalanced grid drop video for proposed solution. These two videos effectively prove the effectiveness of the proposed solution.
