Smart Transformer-Based Single Phase-To-Neutral Fault Management [PDF]
IEEE Transactions on Power Delivery, 2019 The smart transformer (ST), with its high control capability, offers new features for optimizing the management of the distribution grid. The ST, by controlling the voltage in each phase independently, is able to manage the operations during grid faults, in particular in the single-phase ones.

Evaluation of DC-AC Single-Phase Solid-State Transformers [PDF]
IEEE Latin America Transactions, 2019 This work presents an evaluation of three topologies of DC-AC single-phase solid state transformers, for applications in electric microgrids. The main features of these topologies are galvanic isolation, capability to control the power flow bidirectionally, soft switching and unit power factor under open loop control. The principle of operation of each
