Texas Instruments (TI) announced a long-term collaboration with Delta Electronics, a global power and energy management manufacturer, to create next-generation 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 and innovate across EV onboard charging.
“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. “Together with Delta, we will use TI semiconductors to develop EV 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.”
“Delta has been developing highly efficient 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. “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 collaboration to accelerate product development and improve product safety and quality. We look forward to furthering our leadership and creating a win-win situation in the rapidly developing electric vehicle market.”
Three phases of development for next-generation automotive power solutions
- Focusing on EV onboard charging, the collaboration’s first phase is focused on Delta’s creation of an 11kW onboard charger that is more affordable and lighter by utilizing TI’s most recent C2000TM real-time microcontrollers (MCUs) and TI’s exclusive active electromagnetic interference (EMI) filter solutions. Together, the firms are utilizing TI’s technology to achieve up to 95% power conversion efficiency while reducing the charger’s size by 30%.

To allow manufacturers to meet automotive safety integrity levels (ASILs) up to ASIL D, which reflects the strongest automotive safety criteria, TI and Delta will use the most recent C2000 real-time MCUs for automotive applications in phase two. The power density of onboard chargers will be further improved by highly integrated automotive isolated gate drivers, which will also reduce the whole solution size.
- Phase three will see the two companies working together to create the next wave of automotive power solutions, leveraging TI’s more than a decade of expertise in the development and production of products utilizing 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. “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.”
