Universal Minimal Converter — Multiport HF-Link DC/DC/AC
Center for Distributed Energy, Georgia Tech · ECCE 2025
A multiport bidirectional high-frequency-link split-phase DC/DC/AC converter: one high-frequency isolation stage serving several ports, so PV, storage and a split-phase AC output share the same magnetics instead of each needing their own converter.
Approach
- Tri-port architecture around a single high-frequency link.
- Bidirectional DC/AC conversion, single-stage.
- Ultra-low leakage inductance transformer design.
- Sigma-delta modulation for AC synthesis.
- Split-phase output, matching North American residential service.
