“…There are many kinds of topologies to meet the above requirements, such as the split capacitor inverter (SCI) [1,2], four-leg inverter [3][4][5][6][7][8][9], and neutral point forming transformer (NFT) inverter [10,11]. The split capacitors of SCI not only act as support capacitors, but also provide the route of the unbalanced current and ripple current, which means that split capacitors have a larger volume and weight, and the ripple current in support capacitors and filter capacitors is larger than in other structures, which makes the capacitors be vulnerable to the ripple current.…”

In order to improve the control performance of a train auxiliary inverter and satisfy the requirements of power quality, harmonics, and unbalanced factor, this paper proposed a design method of a double closed-loop control system based on a complex state variable structure. The method simplifies the design process and takes full account of the effects of coupling and discretization. In the current closed-loop process, this paper analyzed the limitations of the proportional integral (PI) controller and simplified to P controller. In the voltage closed-loop, the paper employed the PI controller plus the resonant controller, designed the parameters of the PI controller. and analyzed the optimal discretization method of the resonant controller under dq axis coupling. Finally, experiments and simulations were conducted to show that the proposed method can achieve the above improvements.
