TI makes energy storage more efficient with 2-kW bidirectional power reference design for UPS

By Texas Instruments

DALLAS – June 7, 2017 -- Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry’s first 2-kilowatt (kW) isolated bidirectional DC/DC converter reference design for 48-V to 400-V uninterruptable power supplies (UPS) and energy storage systems. Designers can leverage this reference design, which features innovative TI analog and embedded technologies, to achieve greater than 93 percent efficiency in next-generation UPS, energy storage, power banks and battery charger applications.  Download the new reference design today.

An energy efficiency story

The increasing need for renewable energy resources across a variety of markets makes power efficiency more important than ever. Global energy standards and regulations continue to increase pressure on engineers to develop energy-efficient systems, while balancing the need to keep overall system costs low. The isolated bidirectional DC/DC converter reference design empowers designers to increase efficiency over a wide load range for charger and backup converter operations, while reducing system power consumption.

Key benefits of TI’s new isolated bi-directional DC/DC converter reference design

48-V to 400-V range: The industry’s first design to provide support for energy storage supplies with a wide range of input voltages.
Greater than 93 percent efficiency: A fully tested design with TI products to help designers quickly meet ENERGY STAR guidelines and quicken time to market.
Zero voltage switching (ZVS) in boost mode: Innovative DC/DC converters help enable higher efficiency and lower electromagnetic interference (EMI) than traditional hard-switching converters.
Wide low-voltage DC bus range: Designed to charge a wide range of batteries, the design gives engineers flexibility to design with lithium ion (Li-ion), lithium polymer (Li-poly) and lead-acid battery banks ranging from 36 V to 60 V.
Seamless mode changeover: Less than 100 micro-seconds (µS) mode change over from charging to backup mode helps reduce high-voltage hold up capacitor requirements.
