Abstract

In this paper integrated magnetic current balancing (IMCB) cell-based asymmetrically configured Quad-Active-Bridge (QAB) converter is proposed. QAB converter provides high-frequency isolation for a DC-DC stage of solid-state-transformer (SST), as well as provides a modular solution to the SST medium-voltage (MV) dc link. The proposed IMCB cell ensures the current balancing among the three active H-bridges without using any dedicated controller when transferring equal power from MV to low voltage (LV) side. The proposed IMCB cell is the integration of three inductors of the active H-bridges required for power transfer and zero voltage switching (ZVS), which doesn't require extra magnetic volume. Simulation and experimental results are presented to validate the performance.
