Abstract

The quad-port magnetic network energy router (MNER) is a potential solution for the energy dispatch in low-voltage dc applications with the advantages of high efficiency and high control flexibility. Multi-port power decoupling is critical for the reliable and stable operation of quad-port MNERs. This paper proposes a wide-range linear decoupling control (WRLDC) strategy for quad-port MENRs using generalized phase-shift (GPS) modulation. The proposed WRLDC strategy achieves power decoupling via closed-loop linear control of the power-GPS-combined-variable relationship, utilizing a simplified unidirectional coupling model. The proposed WRLDC strategy can effectively decouple the power flows and thereby improve the dynamics of quad-port MNERs. Simulations studies with the professional tool PLECS are conducted and a down-scale quad-port MNER prototype is built in the laboratory. The results both confirm the feasibility and effectiveness of the proposed WRLDC strategy.
