Onsemi and Sungrow boost utility energy storage performance
Renewable energy company Sungrow has adopted Onsemi’s latest EliteSiC SiC hybrid power module technology for the PowerTitan 3.0 energy storage platform.
The PowerTitan 3.0 platform incorporates Onsemi’s high-density power integrated modules (PIMs), optimised for three-level inverter architectures used in high-power energy storage applications.
Compared with the previous-generation platform, the new architecture is said to improve inverter-level efficiency by 0.4 percent, enabling higher-power battery storage deployments without sacrificing efficiency. The architecture supports power conversion units rated up to 450 kW, contributing to the platform’s increased power density and higher-power deployment capability.
According to Onsemi analysis, a 0.4 percent efficiency improvement delivered by the new SiC hybrid module could save more than 475 MWh of energy annually in a 100 MW battery energy storage installation compared with the previous-generation module.
The design win builds on a long-standing relationship between Onsemi and Sungrow. The companies collaborated throughout platform definition, system optimisation and qualification to meet the demanding performance requirements of next-generation energy storage deployments.
