New high-voltage silicon carbide power modules aim to improve efficiency, reduce losses, and simplify next-generation power systems supporting AI infrastructure, renewable energy, and high-power energy conversion applications.
As AI data centres and renewable energy systems rapidly increase electricity demand, the pressure on power conversion infrastructure is growing. Addressing these challenges, Wolfspeed has introduced a new family of 3.3kV silicon carbide (SiC) power modules for medium- and high-voltage applications, targeting improved efficiency and scalability in next-generation energy systems.
The newly launched modules are offered in two industry-standard footprints: a high-power half-bridge baseplate design and a scalable full-bridge baseplate-less architecture. The approach allows system designers to select packaging based on application requirements while reducing design complexity in advanced power systems.
The key features are:
- 3.3kV silicon carbide MOSFET architecture
- Two industry-standard package footprints
- Supports continuous 2kV+ DC-link operation
- Up to 42% lower switching losses
- Optimized for >800A high-current systems
The products are intended to help engineers simplify power architectures by enabling two-level topologies in systems using DC-link voltages above 2kV. Reducing the number of power stages can potentially lower component count, improve overall efficiency, and decrease system size.
The high-power half-bridge configuration is designed for applications exceeding 800A and targets demanding environments such as solar power systems, grid-scale energy storage installations, and wind-energy infrastructure. Meanwhile, the scalable full-bridge design focuses on modular implementations, including solid-state transformers and renewable energy systems that require flexible architectures.
The modules also incorporate fourth-generation SiC technology and packaging features designed for long-term reliability. Continuous 24/7 operation support for 2kV+ DC-link environments, combined with sintered die attachment methods, is intended to improve endurance under high electrical and thermal stress.
Performance improvements are also being highlighted. The devices reportedly deliver up to 42% lower switching losses than competing silicon carbide solutions and more than 90% lower losses than traditional IGBT-based approaches under specific operating conditions. Such gains could help reduce energy consumption and improve power density in high-demand infrastructure deployments.
