Summary: This study introduces a new modified high-gain interleaved boost-flyback converter with pulse frequency modulation. The proposed converter utilizes a four-winding coupled inductor and a switching cell to achieve high voltage gain without requiring a large turn ratio. It provides soft commutation for a wide frequency range, continuous input current with low ripple, and low current oscillation even for low-frequency output voltage ripple. This converter is suitable for low-input voltage applications that require a high step-up gain.

Summary: This article proposes an interleaved coupled-inductor (CI) based bidirectional dc-dc converter (BDC) with a higher voltage conversion ratio (VCR). The CI in this topology can function as both a filter inductor and a transformer, improving power density. The turns ratio of the CI is used to improve VCR and reduce voltage stress. The interleaved technique achieves low current ripple and reduced current stress. The control method employs pulsewidth modulation plus phase-shift (PPS) control, achieving soft-switching and high transmission efficiency.

Summary: A ripple-free bidirectional dc-dc converter is proposed for battery charging/discharging application. The converter achieves zero current ripple on the battery side using two-phase interleaving technology, and effectively achieves high voltage conversion ratio and reduced voltage stresses of switches through series connection. The control variables can be decoupled with fixed duty cycle determined by battery side voltage and monotonously regulated transfer power by phase-shift angle. Theoretical derivation shows soft switching in all switches can be achieved with proper parameter design. Experimental verification of a 40-60V/400V 1-kW prototype demonstrates the merits of the proposed converter.

Summary: Here, a novel modular bidirectional high voltage gain soft-switching DC-DC converter is proposed, which achieves wide range expansion of port voltage and voltage gain by gridded filling of modules and achieves voltage and current sharing among these modules. All semiconductor devices realize full-load soft-switching operation in both power directions by introducing a simple auxiliary zero-current transaction (ZCT) cell in each module. A distributed control system improves the converter's design flexibility and dynamic performance. Moreover, the converter can provide multiple fixed voltage nodes and reduce input current and output voltage ripples through interleaved operation.

Summary: This paper presents a dual transformer-based bidirectional DC/DC resonant converter design, analysis, and control method with balanced voltage stress across all the resonant capacitors. The proposed converter features a dual-rectifier structure on the secondary side, allowing operation over a wide load range with balanced voltage stress. By using two small transformers, transformer stress is greatly reduced, reducing thermal and electrical stress on the windings. The controller consists of a feedforward control part for uncertainty compensation and a feedback control part for error convergence.

Summary: This paper introduces a distributed predictive secondary control strategy that utilizes single-phase reactive power control to share imbalance in AC Microgrids. The innovative approach includes an objective function and dynamic models as constraints, allowing control based on local measurements and neighboring generator information. The proposed distributed model predictive control scheme outperforms other solutions by directly sharing imbalance in terms of single-phase reactive power without adding extra power converters.

Summary: This paper introduces three different algorithms for tracking saliency in seven-phase PMSM to achieve sensorless speed control. The algorithms measure the change of stator currents when different active vectors are implemented using NSV-SVPWM. A comparison between the algorithms in terms of THD is presented, showing that using long active vectors in NSV-SVPWM reduces current distortion. Simulation results analyze the effect of different active vectors on current THD and demonstrate the effectiveness of the proposed control technique post speed sensor failure.

Summary: This article presents a novel scheme based on distributed model-based predictive control for the secondary level control of hybrid ac/dc microgrids. The scheme proposes prediction models based on droop control and power-transfer equations to characterize the generators in both the ac and dc sub-MGs, and power balance constraints are used to predict the behavior of interlinking converters. The proposed scheme is validated through experimental results in various scenarios, including load changes, frequency and voltage regulation, and communication malfunction.
