Design of a bidirectional power converter for charging pile based on V2G
2017 IEEE International Conference on Industrial Technology (ICIT), 2017Co-Authors: Bowen Xu, Hui Wang, Yubin WangAbstract:With the development of electric vehicle and smart grid, charging piles in the future are required to realize the function of Vehicle-to-Grid, which means it can charge and discharge the power battery of stationary electric vehicles. A bidirectional power converter is designed for the V2G charging piles in this paper. First a two Stage topology is applied to the converter. Three-phase bridge converter is employed in the preceding Stage of AC-DC, and dual active bridge converter is employed in the Succeeding Stage of DC-DC. Then corresponding control strategy based on such topology is proposed to meet the demand of bidirectional power flow. Double closed-loop and PQ control is adopted in the AC-DC converter. And single-phase-shift control is adopted in the DC-DC converter. Finally, simulations combining the mentioned converter with battery generic model verify the design that the converter for charging pile can meet the requirements of bidirectional power flowing and charging or discharging of the battery.

Resolving the components of transient signals by a multiStage procedure
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics Speech and Signal Processing, 1992Co-Authors: S. Umesh, D.w. TuftsAbstract:The authors propose a multiStage procedure to achieve good local resolution of significantly overlapping components in a transient signal. The received transient signal is assumed to be a superposition of modulated and time-shifted versions of a single one-sided exponential function whose damping coefficient is known. At each Stage of the proposed procedure the authors coarsely identify (as compared to the next Stage) broad regions in the time-frequency plane that have significant signal energy. These correspond to possible regions where signal components may be present. In each Succeeding Stage, they focus on these coarsely identified signal regions to further identify subregions in them that have significant energy. The detection of signal components in the subregions is done in the presence of possible interference from neighboring regions. Implementation of this method is based on the use of generalized eigenvectors of signal and interference correlation matrices. The detection statistics is a linear combination of the magnitude squared projections of the received data onto the individual generalized eigenvectors.
