Texas Instruments and Delta to Collaborate on EV OBC


Thursday, July 4, 2024

Texas Instruments Inc. (TI) has announced a long-term collaboration with Delta Electronics to create next-generation electric vehicle (EV) onboard charging (OBC) and power solutions.

This work will leverage both companies’ research and development (R&D) 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.

“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. 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,” said Amichai Ron, senior vice president for Embedded Processing at TI.

“Delta has been developing high-efficiency automotive power products, systems and solutions since 2008 to help reduce transportation-related carbon emissions. 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. 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,” said James Tang, executive vice president of Mobility and head of the Electric Vehicle Solutions business group at Delta Electronics.

The collaboration will involve three phases of development for next-generation automotive power solutions. Phase one 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.

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. 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,” said Luke Lee, president of Taiwan, Japan, Korea and South Asia, Texas Instruments.

In line with this collaboration, Delta will establish a joint innovation laboratory with TI to enhance the power density and performance of Delta’s own EV power systems, and ultimately strengthen its core competitiveness in the field of EVs.

In response to the era of software-defined vehicles (SDV), Delta has built up joint labs with several international semiconductor companies that focus on automotive power electronics and digital control, to meet the future innovation and higher requirements for power efficiency and safety in next generation EVs. The joint innovation lab with TI is expected to accelerate development and full validation of Delta’s automotive products to help international car manufacturers develop key architectures and layouts for next-generation EVs with better product quality than the competitors.
