Three-phase/level T-type converter has advantages of high efficiency and low current harmonics, which is utilized in power conversion systems for supplying dc loads widely. Three-phase/level T-type converter provides bipolar dc buses with a neutral line at relatively low cost. In order to extend applications for bipolar dc bus structure, voltage independence control of split-dc bus proposed in this...
The exact battery model has always been a thorny problem in battery management system (BMS). In order to meet the actual working conditions, battery model parameters should be identified from a variety of experimental data (charging, discharging and rest periods). In this paper, we propose a parameter identification method based on iterative learning for the equivalent circuit battery models. This...
Bipolar dc-dc converters, which are widely used in the battery testing equipment, have many advantages such as simple structure, wide range of output voltages and high conversion efficiency. However, the traditional synchronous carrier modulation method leads to a circulating current in the ground wire connected between filtering capacitors and the negative dc input bus. The circulating current results...
The VIENNA rectifiers have advantages of high efficiency as well as low output harmonics and are widely utilized in power conversion system when dc power sources are needed for supplying dc loads. VIENNA rectifiers based on three-phase/level can provide two voltage outputs with a neutral line at relatively low costs. However, total harmonic distortion (THD) of input current deteriorates seriously...
