模块化二极管整流器：固态变压器的新家族

Solid-state transformers (SSTs) are conventionally based on a multistage architecture, with an input and/or an output ac/dc converter (for interfacing with the ac grid and/or the load), and with an isolated dc/dc conversion stage (to provide insulation and voltage/current scaling). Alternatively, some single-stage SST circuits use ac/ac conversion modules and rely on bidirectional blocking devices...
