Accelerating the shift with silicon carbide

Power electronics play a key role in reducing emissions and enabling sustainable energy systems. WBG materials, especially SiC and GaN, are accelerating this transition faster. SiC modules can offer higher breakdown voltages, operate at higher switching frequencies and lower losses than conventional Si devices.

Why opt for SiC?

Greater efficiency

More power from the same footprint

Higher switching frequency and operating temperature

Driving efficiency and performance in heating and cooling

SiC power modules markedly improve efficiency, extend system lifetime and support compliance with stricter energy regulations. They enable higher system performance while reducing energy consumption and emissions.

Use case: PFC converters

  • More compact design

  • More energy efficient

  • Cost savings for system components

  • Use of SiC diodes is crucial

Enabling a faster, more efficient charging infrastructure

Growing demand for fast EV charging is speeding up SiC adoption. With good reason: This technology supports higher power levels, improved efficiency and compact installation footprint, thereby enabling engineers to build robust and sustainable charging networks.

Use case: megawatt charging

  • DC-coupled system at 1500 Vdc, simplifying integration of renewables and ESS

  • Centralized PFC stage, SST connected directly to MV grid and modular DC/DC stage

Tapping the power of renewables

SiC adoption is accelerating, especially in hybrid inverters that combine solar and battery charging in one unit. Still, most SiC use today comes from utility‑scale string inverters and large ESS. Many of these rely on hybrid designs that mix conventional Si with SiC to strike a balance between cost and performance.

Use case: SiC vs. Si diode

SiC diodes are already well-established in hybrid power modules (Si-IGBT with SiC FWD) for PV inverters, particularly utility-scale string inverters. This brings benefits such as the elimination of reverse recovery losses as well as reduced turn-on losses and thermal stress in IGBTs.

  • Eliminated reverse recovery losses in neutral point clamped diodes

  • Reduced turn-on losses in IGBTs and junction temperatures

  • Reduced EMI noise

Use case: SiC MOSFET vs. Hybrid

The significance of SiC MOSFETs has risen, notably in next-generation bi-directional power conversion systems (PCS), as a result of the increased power density, enhanced efficiency, overload capability and reduced operating costs they enable.

  • Superior efficiency due to significant reduction in dynamic losses and comparable conduction losses

  • Better overload capability

  • Reduced cooling efforts

  • Lower operating costs (costs/kWh)
