Modelling and Stability Analysis of 100kW Modular Dual Active Bridge Converter for Robotic Arm-based Charging Systems

This paper presents the stability analysis and control design of the DC-DC stage in a 100 kW modular robotic arm-based off-board charging station. The study derives large and small signal models and defines control design requirements to ensure closed-loop stability. Finally, the performance of the proposed large and small signal models has been validated through time-domain simulation results.
