TI Provides Isolated Bidirectional DC/DC Converter Reference Design
Published2017.06.12 10:42TI has announced the availability of a 2kW isolated bidirectional DC/DC converter reference design for 48V~400V uninterruptible power supply (UPS) and energy storage systems.
This reference design adopts TI's innovative analog and embedded technologies to provide over 93% efficiency in next-generation applications such as UPS, energy storage devices, power banks, and battery chargers.
Through this isolated bidirectional DC/DC converter reference design, developers can design chargers and backup converters that operate across a wide load range with high efficiency and low system power consumption.
This reference design integrates the backup converter and charger into a single power stage, occupying minimal board space to facilitate easier energy transfer in applications requiring wide input ranges such as electric vehicles (EV) and industrial servers. Additionally, by adopting TI's advanced analog technologies such as the 100V NexFET™ CSD19536KCS power MOSFET and the UCC27211A half-bridge gate driver, it delivers high efficiency. The INA240 current sense amplifier provides accurate current measurement capability, while the AMC1301 enhanced isolated amplifier and UCC21520 isolated half-bridge gate driver provide an effective solution for sensing isolated high-voltage rails and driving high-voltage full bridges. The Piccolo™ TMS320F28033 microcontroller implements digital system control.

To shorten the charging time of electric vehicle batteries
The greatest concern for electric vehicles is whether they can operate without running out of "fuel" and travel long distances. The fuel for electric vehicles is, of course, electricity. The fuel issue is related to battery capacity and electric charging stations. Electric vehicles have existed since the 1800s in somewhat different form, and they faced problems that are essentially similar to those we encounter today. In fact, in the early 1900s in the United States, one quarter of produced vehicles were electric vehicles. The reason demand decreased was that the supply and distribution of gasoline was easier than electricity. It took 60 years before the necessity of electric vehicles began to emerge due to environmental concerns. Problems that electric vehicles have not yet resolved include improvements in battery capacity, high-efficiency motors, and public awareness regarding environmental pollution. The issue of easy access to public charging stations and the ability to charge quickly remains significant. To meet market needs, charging stations including DC fast chargers must become as ubiquitous as ordinary gas stations. Additionally, all electric vehicles must be compatible at electric vehicle charging stations.

TI Launches Cost-Optimized Industrial Ethernet SoC
Texas Instruments (TI) announced the launch of a new Sitara™ AMIC SoC product family that enables the implementation of cost-optimized industrial Ethernet communications. The AMIC110 SoC is a multi-protocol industrial communication processor that provides a ready-to-use solution supporting more than 10 industrial Ethernet and fieldbus communication standards. This device utilizes TI's integrated software platform, Processor SDK, for industrial communication support in factory automation and control applications, as well as TI's proprietary programmable industrial communication subsystem (PRU-ICSS) that can be programmed by users. By adding industrial Ethernet functionality using TI's new Sitara AMIC110 SoC, it becomes possible to easily convert existing non-networked designs, such as motor drives, into networked systems. Unlike ASICs that support a single industrial Ethernet standard, the AMIC110 SoC's programmable real-time unit (PRU-ICSS) supports a wide variety of protocols including EtherCAT, Profinet, Ethernet/IP, PROFIBUS master/slave, HSR, PRP, POWERLINK, SERCOS III, and CANopen, with development for additional standards currently underway.
