“…23 Unfortunately, current sharing is of major concern, which may not be achieved without adopting extra circuitry and/or active control schemes. 24 The literature presents numerous interleaved boost converters for distinct practical applications, which may or may not achieve a high voltage gain depending on the circuit configuration. However, this is not the case of interleaved SEPIC topologies, which are available in a much smaller number of publications.…”

This work presents a nonisolated high step‐up single‐ended primary inductance converter (SEPIC) topology for high‐power, high‐current applications. The converter operation is based on the interleaving principle, and the active switches are driven by gating signals phase shifted by 180°, whereas automatic current sharing is achieved owing to an autotransformer with unity turns ratio. It is possible to extend the voltage gain employing voltage multiplier cells (VMCs) composed of diodes and capacitors. Prominent advantages of the structure include low current and voltage stresses on the semiconductors, inherent modularity, better thermal distribution, and reduced dimensions of the filter elements. A comprehensive theoretical analysis is derived, from which a 1‐kW prototype is designed and thoroughly evaluated.

“…However, reverse recovery problem of the output diode still remains unimproved well. The coupled inductor technique solves the reverse recovery problem of the output diode, but it brings a turn-off voltage peak problem of the power switches [24][25][26][27][28][29][30]. To get high voltage gain, the double secondary windings of the coupled inductor were connected in series in the interleaved converters in [29,30].…”

An interleaved parallel high step-up DC-DC converter with cross-coupled inductors for low current/voltage ripple and autocurrent sharing was proposed in this paper. This converter applies interleaved parallel input which decreases the input current ripple significantly. Due to the interleaved coupling effect of three coils of the cross-coupled inductors, this converter can realize automatic current sharing under asymmetric distribution of duty ratio of switch control signal or coupled inductors. By using the leakage inductance of coupled inductors, the proposed DC-DC converter has high voltage gains and small voltage stress of the main switches and output diodes. Moreover, the proposed converter solves the reverse recovery problem of the output diodes at the minimum loss. In addition, its power switches realize zero-current turn on. In this paper, working principle is analyzed thoroughly and performance of this topological circuit is verified through a prototype with 1 kW output.

“…[1][2][3] The interleaved power converters have several benefits, which include the ripple cancelation in current waveforms, lower value of ripple amplitude, passive components size reduction, and the improvement of dynamic response. [4][5][6][7] However, with the increment of the number of parallel phase, it is difficult to control the inductor current of each phase and the output voltage. Hence, to solve this, it is essential to develop advanced control strategies for the interleaved power converters.…”

In this paper, a novel valley V 2 control scheme for interleaved boost converter is presented to improve the transient response performance of system and realize the current sensorless control, and its stability is analyzed by a nonlinear analysis technique. In this proposed methodology, the current sensor is saved by the proposed control signals sharing algorithm, and the nonlinear dynamics is investigated by employing a nonlinear analysis method based on the Monodromy matrix. Meanwhile, the information of the converter parameters' influence on the system stability can be obtained by calculating the Monodromy matrix of switching event. It is worth mentioning that the location of eigenvalues of this matrix can be utilized to analyze the relationship between converter parameters and stability margin. Furthermore, by adopting the knowledge gained from this analysis, an auto-tuning resonant parametric perturbation is proposed to ensure an excellent performance of converter with an extended range of stable operation. Finally, the simulation and experimental results are presented to verify the effectiveness and theoretical analysis of the proposed method.
