DALLAS – Texas Instruments (TI) will showcase technologies that are “unlocking the power of high-voltage technology” at PCIM 2023, May 9-11 in Nuremberg, Germany. TI experts will demonstrate new high-voltage and vehicle electrification innovations, including a new reference design for highly efficient traction inverters. TI will also showcase its high-voltage products, reference designs and engineering expertise in applications for energy storage systems and battery management. Visit TI in Hall 7, Booth No. 459, or see TI.com/PCIM for more information.
Demonstrations will focus on these areas:
- High-voltage technology: GaN- and SiC-based designs, isolation technology
TI will show a new 230-V, 2-kW GaN-based three-phase inverter for industrial applications. The combination of GaN technology, delta-sigma current and voltage sensing and a C2000™ real-time microcontroller (MCU) helps maximize motor-drive performance. A live charging demonstration of a highly efficient, three-phase 11-kW AC/DC bidirectional rectifier/inverter with a GaN and Silicon Carbide (SiC) reference design achieves up to 99% efficiency and power density higher than 2 kW/L. TI will also demonstrate an isolation monitoring reference design based on a resistive network switching method. This solution provides better than 5% accuracy for symmetrical and asymmetrical fault conditions over a wide isolation resistance range.
- Automotive: vehicle electrification
The 800-V, 300-kW SiC-based traction inverter system solution developed by TI and Wolfspeed provides a foundation for original equipment manufacturers and design engineers to create and more quickly bring to market high-performance, high-efficiency traction inverter systems. This demonstration shows how the traction inverter design with TI and Wolfspeed technology improves system efficiency by reducing overshoot in available voltages with TI’s analog and embedded processing products combined with the Wolfspeed SiC power module.
- Renewable energy: energy storage systems
TI will demonstrate the key building blocks of an industrial battery energy storage system (BESS). This demonstration showcases battery cell monitoring, protection and built-in Coulomb counting of stacked and isolated battery cells. A PC GUI communicating with the MCU through a standard Controller Area Network bus displays battery system information. This demonstration will serve as a starting point for engineers interested in designing their own battery management system for an industrial BESS.
- Power management: power density, low EMI, low IQ
TI plans to showcase high power density, low electromagnetic interference (EMI) and low quiescent current (IQ) in designs for power levels ranging from 65 W up to 5 kW. These designs, made possible by TI gallium nitride (GaN) technology, target the highest efficiency and power density. Besides USB adapters for consumer applications, TI will showcase high power-density designs for industrial applications such as USB wall outlets and server power-supply units.
TI will add videos of these demonstrations and more to its PCIM website May 9.
