Solid-State Transformer Topology with Active Harmonic Elimination for Megawatt EV Hubs
By Dr. Hiroshi Tanaka , Dr. David Clark
Electrification of commercial fleet transport mandates multi-megawatt fast-charging substations directly connected to medium-voltage distribution feeders. We present an interleaved silicon-carbide (SiC) dual active bridge (DAB) solid-state transformer (SST) featuring carrier-phase-shifted PWM and selective harmonic mitigation. At 13.8kV grid coupling, the 2.4MW prototype achieves 98.4% peak efficiency and compliance with IEEE 519-2022 total harmonic distortion standards.
