固态变压器子模块电容减容的磁分支缓冲通道及磁模型分析

For a cascaded H-bridge-based solid-state transformer where the isolation stage is a quad active bridge (QAB), this article proposes a magnetic branch snubber channel scheme with zero harmonic impedance/flux. This innovative scheme offers a low-impedance pathway specifically for second-order frequency ripple-current (SFRC), serving as an alternative to traditional large capacitor branch snubber ch...
