“…(3) and (4), the d-axis error current I doff1 and q-axis error current I qoff1 between CSI 1 and CSI 2 are obtained. Note that this calculation is in the controller of CSI 1 , so I d1 and I q1 are in the position of dividend in (3) and (4). Then the error currents between I d1 , I d2 , I q1 and I q2 will be compared with 0 because if there is no circulating current between parallel inverters, the error currents I doffx and I qoffx (x=1,2) will be 0, and the other one purpose is to define the direction of the compensation.…”

“…The current-source inverter (CSI) offers advantages over voltage source inverter (VSI) in terms of inherent boosting and short-circuit protection capabilities, direct output current controllability, and ac-side simpler filter structure [1], [2]. These features make it attractive in many UPS applications [3], such as high speed elevators, high-power electric drives and distributed generation systems as an interface between the utility grid and distributed power sources [4].…”

In this paper, a multilevel current-source inverter (MCSI) topology is analyzed. The issue of constructing a novel modular single-rating inductor MCSI is explored, taking advantage of the features of field-programmable gate arrays (FPGA) for control and gate signal generation. The proposed topology is built with identical modules where all inductors carry the same amount of current, simplifying the construction and operation of industrial applications with higher efficiency. A new statemachine approach, which is easy to implement in an FPGA, and a proper implementation of the phase-shifted carrier sinusoidal pulse width modulation (PSC-SPWM) allow both current balance in all modules and effective switching-frequency minimization. The performance of the MSCI proposed is simulated with Matlab and is verified by constructing a prototype.Index Terms-Field-programmable gate array (FPGA), multilevel current-source inverter (MCSI), phase-shifted carrier SPWM (PSC-SPWM).

“…Besides, there is a potential risk of overcurrent due to the phase-leg short circuit, which reduces the system reliability. On the other hand, the current source converters have the inherent current limiting capability and thus enhance the reliability [8][9][10][11]. Furthermore, they allow forbidden states in the case of voltage source converters that may cause short-circuit, being in case of current source a desirable possibility to achieve soft-switching operation [12].…”

Abstract-Back-to-back converters have been typically used to interconnect the microgrids. For a back-to-back current source converter, the dc-link current ripple is one of the important parameters. A large ripple will cause the electromagnetic interference, undesirable high-frequency losses, and system instability. Conventionally, with a given switching frequency and rated voltage, the current ripple can be reduced by increasing the dc-link inductor, but it leads to bulky size, high cost and slow dynamic response. In order to solve this problem, this paper reveals that the current ripple can be significantly reduced by adjusting the gate patterns of space vector modulation (SVM) between the rectifier and inverter in a back-to-back converter. The experimental results verify the effectiveness of the proposed method.
