onsemi’s EliteSiC family of silicon carbide
(SiC) technologies enhance performance of Ampt’s DC optimizers
onsemi (Nasdaq: ON), a leader in intelligent power and
sensing technologies, and Ampt LLC, the world’s number one DC
optimizer company for large-scale photovoltaic (PV) solar and
energy storage systems, today announced their collaboration to meet
the high demand for DC string optimizers. Ampt uses onsemi’s
N-Channel SiC MOSFET, part of the EliteSiC family of silicon
carbide (SiC) technologies, in its DC string optimizers for
critical power switching applications.
Ampt string optimizers are used in large-scale PV power plants,
enabling lower-cost and higher performing solar and DC-coupled
energy storage systems that are collocated within the solar power
plant. The string optimizers deliver power from the PV array at a
high and fixed voltage for system voltages ranging from 600 to 1500
VDC, reducing the overall current requirements and cost of the
power plant. Ampt optimizers enable higher round-trip – charging
and discharging – efficiency in the energy storage system and solar
power plant by leveraging onsemi’s latest SiC MOSEFT technology
with lowest ON resistance and switching loses.
“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 offers an RDS(on) of 80 mΩ nominally and a
low gate charge (Qg) value of 56 nC along with lower Rg of 1.7Ohms.
It is capable of operating at junction temperatures of 175°C,
reducing the thermal management requirements in applications,
resulting in smaller, lower cost 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 president and general manager, 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.”
