Capacity across the supply chain in power electronics refers to the ability of suppliers, manufacturers, and distributors to meet the demand for power electronic components, systems, and services. It involves ensuring sufficient production capacity, reliable sourcing of materials, and efficient distribution channels to support the industry's growth and requirements.

Silicon MOSFETs and IGBTs (Insulated Gate Bipolar Transistors) are evolving to meet future power electronics needs. Advancements focus on improving efficiency, power density, switching speeds, and thermal performance for a wide range of applications.

Developments in wide-bandgap (WBG) materials like SiC (silicon carbide), GaN (gallium nitride) and newcomers such as Ga2O3 (gallium oxide) promise higher efficiencies, faster switching speeds, and increased power density to power electronics.

GaN (gallium nitride) is beginning to move into new and higher power applications bringing its high efficiency, fast switching speeds, and compact size to electric vehicles, renewable energy, data centres, and more.

Power electronics plays a vital role in upgrading the power grid by enabling advanced control, conversion, and integration of renewable energy sources.

System reliability in power electronics is ensured through rigorous testing. Methods such as thermal, electrical, and environmental stress testing help identify failure modes and improve product quality for consistent performance and longevity.
