ON Semi (NASDAQ: ON), a leader in smart power and smart sensing technologies, and Ampt LLC, the world's number one DC optimizer company for large photovoltaic (PV) solar and energy storage systems, announced a partnership to meet the high demand for DC string optimizers. Ampt uses ON Semiconductor's EliteSiC family of silicon carbide (SiC) technology N-channel SiC MOSFETs in its DC string optimizers for critical power switching applications.
Ampt string optimizers are used in large-scale PV plants, enabling lower cost, higher performance solar and DC-coupled energy storage systems to be deployed together in solar plants. The string optimizer delivers power from PV arrays at high fixed voltages with system voltages ranging from 600 VDC to 1500 VDC, reducing the overall current requirements and cost of the plant. ampt optimizers utilize ON Semiconductor's latest SiC MOSEFT technology with extremely low on-resistance and switching losses to achieve higher bi-directional charge/discharge efficiency for energy storage systems and solar plants.
Incorporating ON Semiconductor's EliteSiC technology into our DC optimizer helps developers of large PV plants improve the economics of their projects," said Levent Gun, CEO of Ampt. Clearly, product performance is a key decision point for us, and ON Semiconductor's provision of technical support at the design stage and ongoing supply assurance to support Ampt's rapid expansion has proven to be a strong partner."
The EliteSiC device has a typical RDS(on) value of 80 mΩ, a gate charge (Qg) value of 56 nC and a low Rg of 1.7 Ohms. It is capable of operating at a junction temperature of 175°C, reducing the thermal management requirements of the application, resulting in a smaller size and lower cost solution
Our EliteSiC technology combines high performance and high reliability to enable the efficient, reliable DC optimizers that industry leaders like Ampt expect," said Simon Keeton, executive vice president and general manager of Power Solutions at ON Semiconductor. We look forward to continuing to work together to develop new products that will propel renewable energy applications forward and create a sustainable ecosystem."
