- Understanding the Energy Storage System in Residential and Commercial Systems
- Use Silicon Carbide to Improve the Efficiency
- Applications and Topologies
The two key renewable energy sources, solar and wind, are inherently dynamic and unstable, requiring energy storage systems (ESS) for grid stability. This paper describes single-phase residential and three-phase commercial power conversion systems (PCS) with a comprehensive discussion on AC-coupled and DC-coupled topologies. The paper compares design approaches, such as between the use of higher voltage switches and three-level circuit configurations, as well as technology approaches, such as Silicon IGBTs, Silicon Carbide (SiC) MOSFETs, and Power Integrated Modules (PIMs). For each functional block, you will also learn about the design advantages from using onsemi’s product offerings of IGBT and SiC power modules, SiC MOSFETs and diodes, IGBTs, gate drivers, signal conditioning and control, logic and memory, and interface devices.
