50kW SiC-based modular solid-state transformer for medium-voltage applications reference design

Overview

TopologyBuck Converter
Input voltage4.2-17 V
Switching frequency5-10 kHz
IC revisionJune 2026

Description

This design implements a three-phase solid-state transformer (SST) based on a silicon carbide (SiC) power module. Using a modular architecture allows for stacking multiple converter submodules in series to meet medium-voltage grid requirements. Using fast switching SiC devices enables the DC/AC stage to switch at 10kHz and the dual active bridge (DAB) isolation stage at 100kHz, which reduces the size of the high-frequency magnetic components and increases the overall power density. Inter-module communication provide the high isolation voltage levels required in medium-voltage end equipment. The cascaded topology distributes the grid voltage evenly across submodules, allowing the use of standard lower-voltage rated SiC devices while maintaining full medium-voltage operation.

Features

50kW rated reference design with modular and scalable architecture.Medium-voltage DC link rated at 2.2kV, low voltage DC link at 1.5kV.SiC power module based H-Bridge converter on the medium-voltage side.Dual active bridge (DAB) for isolated DC/DC conversion stage switching at 100kHz.DC/AC converter switching at 10kHz in unipolar mode.Fiber optic communication between submodules providing the required isolation voltage.Bidirectional power flow capability supporting gridto-storage and storage-to-grid operation.Single module dimensions: 850mm × 300mm × 80mm.

Typical applications

  • Solid State Transformer (SST)
  • Power Conversion system (PCS)
  • Central inverter
  • Energy Storage System
