Texas Instruments - Experts & Thought Leaders

Texas Instruments (TI) announces a long-term collaboration with Delta Electronics, a global power and energy management manufacturer, to create next-generation electric vehicle (EV) onboard charging and power solutions. This work will leverage both companies' research and development capabilities in power management and power delivery in a joint innovation laboratory in Pingzhen, Taiwan. Together, TI and Delta aim to optimize power density, performance and size to accelerate the realization of safer, faster-charging and more affordable EVs. Widespread adoption of electric vehicles "The transition to electric vehicles is key to helping achieve a more sustainable future, and through years of collaboration with Delta Electronics, we have a solid foundation to build upon," said Amichai Ron, Senior Vice President for Embedded Processing at TI. Amichai Ron adds, "Together with Delta, we will use TI semiconductors to develop EV power systems like onboard chargers and DC/DC converters that are smaller, more efficient and more reliable, increasing vehicle driving range and encouraging more widespread adoption of electric vehicles." Developing electric vehicle market "Delta has been developing high-efficiency automotive power products, systems and solutions since 2008 to help reduce transportation-related carbon emissions," said James Tang, Executive Vice President of Mobility and Head of the Electric Vehicle Solutions business group at Delta Electronics. He adds, "Through the establishment of this joint innovation laboratory with TI, Delta intends to leverage TI's abundant experience and advanced technology in digital control and GaN to enhance the power density and performance of our EV power systems." James Tang continues, "With more leading-edge product development and design capabilities, we aim to achieve closer technology exchange and collaboration to accelerate product development and improve product safety and quality. We look forward to furthering our technology leadership and creating a win-win situation in the rapidly developing electric vehicle market." Automotive isolated gate drivers Phase one for the collaboration focuses on Delta's development of a light-weight, cost-effective 11kW onboard charger Phase one for the collaboration focuses on Delta's development of a lighter-weight, cost-effective 11kW onboard charger, using TI's latest C2000™ real-time microcontrollers (MCUs) and TI's proprietary active electromagnetic interference (EMI) filter products. The companies are working together using TI's products to reduce the charger's size by 30% while achieving up to 95% power conversion efficiency. In phase two, TI and Delta will leverage the latest C2000 real-time MCUs for automotive applications to enable automakers to achieve automotive safety integrity levels (ASILs) up to ASIL D, which represents the strictest automotive safety requirements. Highly integrated automotive isolated gate drivers will further enhance the power density of onboard chargers, while also minimizing overall solution size. Building strong connection In phase three, the two companies will collaborate to develop the next generation of automotive power solutions, capitalizing on TI's more than 10 years of experience in developing and manufacturing products with gallium nitride (GaN) technology. "The rapid growth of electronics in automotive applications has enabled more feature-rich, efficient and safer vehicles. However, technical challenges remain," said Luke Lee, President of Taiwan, Japan, Korea and South Asia, Texas Instruments. Luke Lee adds, "Having been in Taiwan for 55 years, coupled with decades of experience in automotive power management, TI has built a strong connection with the local automotive industry. Establishing this collaboration and joint innovation laboratory with Delta is just one more way TI is driving vehicle electrification forward."

Texas Instruments (TI) has introduced the industry's first 650V three-phase GaN IPM for 250W motor drive applications. The new GaN IPM addresses many of the design and performance compromises engineers typically face when designing major home appliances and heating, ventilation and air-conditioning (HVAC) systems. The DRV7308 GaN IPM enables more than 99% inverter efficiency, optimized acoustic performance, reduced solution size and lower system costs. It is on display at the Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM) Conference, held from June 11-13, 2024, in Nuremberg, Germany. High-voltage home appliances and HVAC systems “Designers of high-voltage home appliances and HVAC systems are striving to meet higher energy-efficiency standards to support environmental sustainability goals around the world,” said Nicole Navinsky, Motor Drives Business Unit Manager at TI. Nicole Navinsky adds, “They are also addressing consumer demand for systems that are reliable, quiet and compact. With TI's new GaN IPM, engineers can design motor driver systems that deliver all of these expectations and operates at peak efficiency.” Improve system efficiency and reliability with TI GaN Worldwide efficiency standards for appliances and HVAC systems such as SEER, MEPS, Energy Star and Top Runner are becoming increasingly stringent. The DRV7308 helps engineers meet these standards, leveraging GaN technology to deliver more than 99% efficiency and improve thermal performance, with 50% reduced power losses compared to existing solutions. The DRV7308 achieves industry-low dead time and low propagation delay In addition, the DRV7308 achieves industry-low dead time and low propagation delay, both less than 200ns, enabling higher pulse-width modulation (PWM) switching frequencies that reduce audible noise and system vibration.  These advantages plus the higher power efficiency and integrated features of the DRV7308 also reduce motor heating, which can improve reliability and extend the lifetime of the system. Advanced integration and high power density reduce solution size and costs Supporting the trend of more compact home appliances, the DRV7308 helps engineers develop smaller motor drive systems. Enabled by GaN technology, the new IPM delivers high power density in a 12mm-by-12mm package, making it the industry's smallest IPM for 150W to 250W motor-drive applications. Because of its high efficiency, the DRV7308 eliminates the need for an external heatsink, resulting in motor drive inverter printed circuit board (PCB) size reduction of up to 55% compared to competing IPM solutions. The integration of a current sense amplifier, protection features and inverter stage further reduces solution size and cost. This high-efficiency, high-voltage GaN IPM is the latest example of TI innovations to help solve engineering challenges and transform motor designs. TI's reliable high-voltage technology at PCIM 2024 Visitors to PCIM can see new products and solutions from TI that are enabling the transition to a more sustainable future with reliable high-voltage technology in Hall 7, Booth 652. In addition to the DRV7308 GaN IPM, TI highlights at PCIM include: Next-generation electric vehicle (EV) propulsion system: TI is demonstrating a new 800V, 750kW SiC-based scalable traction inverter system for EV six-phase motors, in collaboration with EMPEL Systems. The demonstration features high power density and efficiency using TI's high-performance isolated gate drivers, isolated DC/DC power modules and Arm® Cortex®-R MCUs. TI's Manager of high-voltage power systems applications, Sheng-Yang Yu, will speak on June 11 in the Markt & Technik panel discussion: ‘Will SiC ultimately Hold its Own against GaN?.’ TI's Manager of renewable energy systems, Harald Parzhuber, will speak on June 12 in Bodo's Power Systems panel discussion: ‘GaN Wide Bandgap Design, the Future of Power.’
