用于中压直流电网的五电平有源中点钳位DC/DC变换器

This paper proposes a five-level active-neutral-point-clamped (5L-ANPC) dc/dc converter for applications in medium-voltage dc grids. A modulation strategy is proposed for the 5L-ANPC dc/dc converter to generate multilevel voltage waveforms, which can effectively reduce voltage change rate $\text{dv/ dt}$, reduce voltage stress on the transformer, and thus reduce the electromagnetic interference a...
