Conversion Efficiency of the Buck Three-Level DC–DC Converter in Unbalanced Bipolar DC Microgrids

IEEE Transactions on Power Electronics, 2020
This article evaluates the power conversion efficiency of the buck three-level dc–dc converter, when operating in unbalanced bipolar dc microgrids. Bipolar dc microgrids adopt a positive, neutral, and negative wire to double the power transfer capability, reduce conduction losses, and provide two voltage levels.

Comparison of Voltage Balancers for DAB Converters in Bipolar Residential DC Microgrids

IECON 2025 – 51st Annual Conference of the IEEE Industrial Electronics Society
Bipolar dc microgrids have been increasingly adopted in different applications due to their versatility in scaling to higher power levels while maintaining the same safety requirements as lower voltage unipolar ones. On the other hand, power imbalance, commonly faced in bipolar systems, can lead to undesirable voltage deviations that may trigger ...

Coordinated control of multiple voltage balancers in a Bipolar DC microgrid

2017 IEEE Power & Energy Society General Meeting, 2017
For the neutral-point voltage balancing control in a bipolar dc microgrid, a coordinated control strategy which is composed of droop method and disturbance observer based current feed-forward has been proposed for parallel operation of multiple voltage balancers.

Bipolar-type DC microgrids for high-quality power distribution

2018
During the last decades, AC systems dominated the power transmission and distribution applications almost exclusively. However, a recent convergence of needs originated in different sectors (renewable energy conversion, information technology and transportation) have accelerated the development of DC systems.

Design and control of utility grid-tied bipolar DC microgrid

International Journal of Emerging Electric Power Systems
Abstract This paper explains in detail the design and control of a utility grid-connected bipolar DC microgrid, which consists of a solar photovoltaic system (SPV), a wind energy conversion system (WECS), a battery energy storage system (BESS) at the DC bus, and a three-level neutral point clamped (NPC) converter to connect the DC ...
