Abstract
Dual active bridge (DAB) converters are pivotal in applications requiring bidirectional power flow, such as automotive and aerospace systems. The input series and output parallel (ISOP) configuration addresses the need for higher output currents by reducing the voltage stress on individual modules, yet it faces challenges like slow dynamic response, parameter sensitivity, and difficulties in maintaining output current sharing amid component mismatches and input disturbances. This study establishes an evaluation framework to quantify current-sharing risks in ISOP-DAB systems under extended phase shift (EPS) modulation, analyzing how inductance discrepancies and input voltage dispersion propagate uncertainties and define risk boundaries. By developing a parameter-uncertainty model and applying a multi-objective genetic algorithm, the research concurrently optimizes inductor current stress and the reflux of power. MATLAB simulations validate the theoretical derivations, demonstrating effective current sharing and enhanced performance under multivariable uncertainties. The conclusions confirm the framework's accuracy in guiding the robust design of ISOP-DAB converters, achieving a balance between operational stability and efficiency.
This paper presents the comprehensive design, analytical modeling, and simulation validation of a dual active bridge (DAB) converter for bidirectional power interfaces in microgrid applications. The proposed analysis is developed under single phase shift (SPS) modulation and is based on the voltage applied across the l...

With the increasing dc-bus voltage level and power rating in renewable-energy applications, dual-parallel five-level active neutral-point-clamped (5L-ANPC) inverters have attracted growing attention because they can increase system capacity and improve output current quality. However, under asynchronous strategy, the d...
The increasing penetration of renewable energy in active distribution networks introduces severe power fluctuations and uncertainties. This challenges traditional scheduling methods that rely on conservative and static capacity boundaries of converter-interfaced equipment. This paper proposes a multi-time-scale secure...

The high rate of replacement of synchronous machines by inverter-based resources (IBRs) has increased the role of Dynamic Voltage Support (DVS) during grid disturbances, especially on weak and failed grid conditions. Traditional reactive-current-based grid-support rules can have a poor performance with large R/X ratios...
