Introduction to Solid-state transformer (SST)

As global electricity demand surges—driven by data centers, transport electrification, growing industrial use, and rising cooling needs—traditional power grids face significant strain. Solid-state transformers (SSTs) offer a game-changing solution, redefining how public grids connect to end devices. SSTs leverage advanced semiconductor technology to create a universal power electronic stack, replacing traditional architectures based on low-frequency transformers. As a global leader in power electronics, Infineon empowers energy-efficient SST designs. With a comprehensive, ready-to-use portfolio, Infineon covers everything from power conversion and microcontrollers to security, auxiliary power supply, sensing and communication.

Solid-state transformer (SST) applications and use cases

SSTs offer transformative benefits across high-impact applications:

  • In AI data centers, SSTs provides facility-level powering of IT racks, saving valuable space and enabling denser IT rack clustering. SSTs also lower total cost of ownership through greater efficiency and scalability.
  • For Electric Vehicle (EV) charging, they minimize substation footprint and copper use, reducing costs and complexity. They also support bidirectional power flow, enabling enhanced grid services.
  • In Photovoltaic (PV) systems, they integrate solar energy efficiently by managing variable output, enhancing grid stability, and supporting advanced energy management.
  • For Battery Energy Storage Systems (BESS), they improve efficiency with bidirectional power flow, voltage regulation, and seamless integration with renewables for reliable energy storage.
  • In industrial DC microgrids, e.g. in cities and factories, SSTs integrate distributed energy resources, support bidirectional power flow, and offer real-time monitoring, creating smarter and more resilient grids capable of managing dynamic loads.

Infineon’s scalable power modules, robust drivers, sensing, and secure control empower manufacturers to create SST platforms that exceed efficiency, grid compliance, and uptime requirements for mission-critical systems.

MOSFETs, IGBTs, diodes, thyristors and gate drivers for SST 

Infineon drives system value and enables design differentiation by focusing on power density, system cost savings, and highly reliable subcomponents. We offer a comprehensive portfolio for today's and next-generation solid-state transformers.

Our portfolio spans discrete and module packages in silicon and silicon carbide, designed for long-term performance while delivering higher efficiency, power density, and cost savings: CoolSiC™ MOSFETs, IGBT,  diodes and thyristors.

CoolSiC™ MOSFET EasyPACK™ modules are enhanced with robust .XT technology and are engineered to meet the demands of solid-state transformers.

Infineon’s EiceDRIVER™ gate driver ICs integrate protection features such as fast short‑circuit protection (DESAT), active Miller clamp, shoot‑through protection, fault reporting, shutdown, and over‑current protection. These capabilities make the drivers well‑suited for both silicon and wide‑bandgap power devices, including CoolSiC™.

Control and auxiliary functions

Infineon’s microcontroller portfolio offers a wide range of state‑of‑the‑art 32‑bit MCUs that deliver strong performance, functional safety, and future‑proven security solutions. PSoC™ 32‑bit MCUs based on Arm® Cortex®‑M cores, designed to bring your ideas to life. AURIX™ leading 32‑bit MCUs for demanding industrial applications, based on TriCore™.

For auxiliary functions, Infineon offers high‑ohmic CoolSiC™ and CoolSET™ MOSFET discretes.

OPTIGA™ security solutions provide a scalable portfolio of embedded security, combining hardware, software, and services to protect data and devices and support secure connectivity.

For boot storage and data logging, Infineon offers high‑performance industrial memories. For current measurement, XENSIV™ high‑precision coreless current sensors provide accurate and stable current sensing.

Infineon’s expertise ensures efficiency, lifetime performance, and cost‑effectiveness for a resilient, sustainable energy infrastructure.
