“…Although the separate controller usage in both decentralized and centralized methods provides a stable operation under parameter mismatch, the common duty ratio techniques that lead to extremely simple implementation also exist in the literature [17]- [19]. The common duty ratio technique was first presented in [17].…”

In this paper, a super twisting sliding mode control method (ST-SMC) is proposed for an isolated input series output parallel current source converter (ISOP-CSC). The main idea behind the input series output parallel connection is to share the input voltage and output current among the converter cells. Since the input current of each cell has to be identical, the control strategy should be able to provide an accurate phase angle to each cell at the same time. The decentralized control method requires a current sensor for each cell. Therefore, the controller performance can be affected by faults, measurement errors, and noises in the slave cell's current sensor. To overcome this issue, the proposed ST-SMC method generates the phase shift between the primary side switching signals of the master cell. After that, the generated phase shift value is transferred to the slave modules. Thus, the same phase angle value is used for each cell and the current sensor is only needed for the master cell. Furthermore, the proposed method doesn't need any voltage sensor. The effectiveness of the proposed control method is investigated by experimental studies that are performed on an ISOP-CSC prototype. The results reveal that the proposed method successfully regulates the input current to reference value under both steady-state and dynamic transition conditions.INDEX TERMS Isolated input series output parallel current source converter, sliding mode control, current control.

“…Modular DC-DC power conversion architectures, which incorporate two or more individual modules in various series/parallel configurations, have been demonstrated to provide efficient and reliable solutions for a range of applications, including renewable energy systems, distributed power systems, and specialized switched-mode DC power supplies. Four fundamental connection arrangements for modular DC-DC converters have been extensively studied in existing literature: parallel-input/parallel-output (PIPO) [1][2][3][4], parallel-input/series-output (PISO) [5][6][7][8][9], series-input/paralleloutput (SIPO) [10][11][12][13][14][15][16][17][18], and series-input/series-output (SISO) [12,14,19,20]. These studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] offer a snapshot of recent publications on these four fundamental arrangements, which also serve as a gateway to earlier works.…”

This study investigates the application of peak current-mode control to a dual-module, independent-input, series-output boost DC-DC converter characterized by mismatched inductors. The converter, operating in continuous-conduction mode, incorporates nonidentical modules, each supplied by a distinct voltage source while their outputs are interconnected in series. A small-signal state-space averaged model, useful for individual module control, is proposed. Utilizing this model, both direct and crosscoupling control-to-output voltage small-signal responses under inductor mismatch are generated with MATLAB assistance. A conventional Type-2 Proportional-Integral controller is designed for the module voltage loop, guided by the direct control-tooutput voltage responses. The impact of inductor mismatch on the transient performance of the module input current and output voltage under step changes in the load current and module source voltage is examined. The cycle-by-cycle simulations conducted via PSIM demonstrate significant agreement with the model predictions.
