通过调节直流母线电压和有源单元提高MMC前端AC-DC变换器固态变压器效率

The inefficiency of solid-state transformers (SSTs) under medium (or light) loads poses a significant challenge for wide power range applications, which leads to reduced energy utilization, increased electricity costs, and potential reliability issues. To solve this problem, this article proposes an SST efficiency improvement strategy considering full power range. The SST utilizes a full-bridge mo...
