Dynamic EV charging mode to support LVDC Microgrid operation

The rapid proliferation of Distributed Energy Resources (DERs) and Electric Vehicles (EVs) has accelerated the adoption of Low-Voltage Direct Current (LVDC) microgrids (MGs). Efficient control of DC fast chargers within these networks is critical for maintaining system stability and efficient operation. This paper pres...

Conceptualization of a DC-LVRT for PEM Electrolyzers: Experimental Validation of a Noninverting Buck–Boost Converter With Feedforward Mode-Transition Compensator

This article introduces and validates the concept of DC low-voltage ride-through (DC-LVRT) for critical DC loads through the utilization of a noninverting buck–boost converter (NIBBC), acting as a front-end converter in the DC power chain for powering polymer electrolyte membrane hydrogen electrolyzers. The objective o...
