Energy Infrastructure

Energy infrastructure refers to the interconnected systems used to generate, convert, store, transmit, and distribute electrical energy. These systems are evolving rapidly due to electrification and renewable integration, requiring higher efficiency, reliability, and scalability across diverse industrial and utility environments. 

High efficiency reduces power losses, improves thermal performance, and lowers operating costs in energy infrastructure systems. As power demand grows and renewable energy adoption increases, efficient conversion and distribution are essential to meet power density targets and regulatory requirements while minimizing system size and total cost of ownership. 

Solid-state circuit breakers replace mechanical contacts with semiconductor switching, enabling ultra-fast response, arc-free operation, dynamic adjustability, and remote monitoring. onsemi notes that these advantages make them suitable for AC systems, hot-swap designs, and high-voltage DC applications.

A battery energy storage system stores energy and releases it when needed to improve renewable integration, grid flexibility, and system reliability. onsemi highlights both AC-coupled and DC-coupled BESS architectures and positions advanced SiC, IGBT, gate-driver, and sensing solutions as core building blocks.

Power electronics enable precise control of electrical energy by converting, regulating, and managing power flow between sources, storage, and loads. Technologies such as converters and advanced semiconductors improve efficiency, reduce losses, enhance grid resilience, and enable flexible power routing in modern electrified systems. 

A solar inverter converts variable DC energy from the PV side into grid-compatible AC power. onsemi identifies efficiency, reliability, safety, and thermal performance as critical requirements across residential, commercial, and utility-scale solar designs.

onsemi highlights advanced SMPS approaches such as Totem-Pole PFC, LLC resonant converters, synchronous rectification, and quasi-resonant flyback control. These are paired with SiC and GaN devices to improve efficiency and support compact power supply designs from lower wattage systems to multi-kilowatt platforms.

onsemi emphasizes advanced SiC technology, packaging innovation, scalable power architectures, and efficient thermal management as major ingredients for DC fast EV charging. The company also points to 3-phase PFC and active front-end topologies as important charger design elements.

Wide-bandgap devices such as silicon carbide (SiC) deliver higher switching frequencies, lower conduction losses, and improved thermal performance compared with silicon. This enables higher efficiency, smaller system size, and better reliability, making them ideal for high-power applications like solar, storage, and EV charging systems. 

onsemi describes its system solution guides as detailed, practical development resources that help decode product complexity, streamline project development, and provide technical advice for real system architectures. The guides are presented as tools to accelerate design and innovation across multiple markets.
