一种兼顾高效率与控制灵活性的混合模块化直流固态变压器

This article presents a hybrid modular dc solid-state transformer (HMDCSST) composed of a series resonant dual active bridge (SR-DAB) and a phase-shift dual active bridge (PS-DAB), aiming at improving the transfer efficiency as well as maintaining the control flexibility key problems in terms of modeling and control strategy are discussed in this article. The generalized average and small-signal m...
