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
