Alencon releases new high-voltage DC:DC converters
Alencon Systems has announced the launch of the CUBE, the latest line of high power, high voltage DC:DC converters for alternative energy applications. The CUBE, which stands for Combined Universal Buck/Boost Power Electronics, is a compact, centralized DC:DC optimizer. The CUBE is available to support both 1,000 and 1,500 V DC:DC applications and is available in two modalities: the CUBE-PV for solar applications and the CUBE-ES for battery energy storage applications.
The CUBE is unique among other centralized DC:DC converters by providing a power density approximately five times greater than other non-isolated DC:DC converters in a comparable power class. The CUBE achieves its unparalleled power density through a silicon carbide powertrain. The CUBE is currently patent pending with the United States Patent Office. Like all Alencon products, the CUBE is designed and built in the United States at Alencon’s Philadelphia facility.
The CUBE offers alternative energy project developers a number of unique benefits. For large-scale PV installations, the CUBE-PV provides distributed energy harvesting to increase energy yield for projects with larger central inverters. For such projects, the CUBE will increase the voltage to a central inverter so that the inverter can be used better. This allows large-scale PV installations to be built with fewer power blocks and thus significantly lower costs. By operating at higher voltage and lower current, the CUBE-PV also ensures that less copper is used in the balance of the system. In addition, the CUBE-PV ensures that PV installations are ready for storage. The CUBE-PV can also be a great tool to power older PV arrays.
For battery energy storage applications, the CUBE-ES provides a highly compact, cost-effective package for integrating batteries into DC-coupled solar and storage projects. The CUBE-ES is an ideal solution for ramping up the voltage from lower voltage batteries to higher voltage power conversion systems (PCS). Due to its high switching frequency, the CUBE provides very little additional fault current contribution to an energy storage system.
“The introduction of the CUBE series of DC:DC converters enables Alencon to provide alternative energy project developers with yet another unique tool in an increasingly DC-connected world,” said Alencon Systems president Hanan Fishman. “Alencon has used its decades of expertise in building high-performance, high-voltage DC:DC converters with next-generation silicon carbide power electronics to bring to market a product with unparalleled power density.”
The Alencon CUBE series complements Alencon’s existing line of galvanically isolated modular DC:DC optimizers, the SPOT and BOSS. For example, the CUBE-PV can be coupled with the Alencon BOSS to create cost-effective solar + fixed voltage storage DC bus projects.
