PHOENIX as well Fort Collins, Colo. The date is Jan. 5 2023 onsemi (Nasdaq ON) is a pioneer in sensing and intelligent power technologies as well as Ampt LLC, the world’s top DC optimizer that specializes in massive-scale photovoltaic (PV) solar and energy storage systems today announced their partnership to address the need in DC string optimizers. Ampt utilizes the onsemi N-Channel SiC MOSFET that is which is part of the EliteSiC series that includes silicon carbide (SiC) technologies, to create their DC string optimizers for vital electrical power switch applications.

Ampt String Optimizers can be employed for large PV power plant, which allows less expensive and more efficient batteries for DC and solar devices that are located within an solar power plant. The string optimizers draw the power generated by the PV array with a fixed and high voltage to system voltages that range between 600 and 1500 VDC, thus reducing the overall power requirements and costs for the plant. Ampt optimizers enable greater round-trip charging and discharging efficiency of the storage of energy as well as solar power plant through leveraging onsemi’s most recent SiC MOSEFT technology, which has the lower ON resistance and less switching losses.

“Incorporating onsemi’s EliteSiC technology into our DC optimizers helps utility scale solar developers and owners improve their project economics,” said Levent Gun, CEO of Ampt. “Clearly, the product performance was a critical decision point for us, but onsemi’s technical support during the design phase and their ongoing supply assurance to support Ampt’s rapid scaling are the hallmarks of a strong partner.”

The EliteSiC device comes with the following features: an RDS(on) of 80m nominally, and a low gate charge (Qg) value of 56 nC , as well as a less Rg that is 1.7Ohms. It can function in junction temperature of 175degC. which reduces the need for thermal management in various applications, leading to smaller, less expensive solutions.

“The combination of performance and reliability of our EliteSiC technology enables efficient and dependable DC optimizers and is what an industry leader such as Ampt expects,” said Simon Keeton, executive vice general manager and president, Power Solutions Group, onsemi. “We look forward to a continued collaboration on new products that drive renewable energy applications forward on our journey to a sustainable ecosystem.”
