Dallas-based semiconductor giant Texas Instruments is collaborating with Taiwan’s Delta Electronics, a global power and energy management manufacturer, to create next-generation electric vehicle onboard charging and power solutions.

The companies said this collaboration will leverage their research and development capabilities in power management and power delivery in a joint innovation laboratory in Pingzhen, Taiwan. Together, TI and Delta said they aim to optimize power density, performance, and size to accelerate the development 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,” Amichai Ron, SVP for Embedded Processing at TI, said in a statement. “Together with Delta, we’ll 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.”

Delta Electronics has a location in Plano.

Reducing carbon emissions while enhancing power

“Delta has been developing high-efficiency automotive power products, systems and solutions since 2008 to help reduce transportation-related carbon emissions,” said James Tang, EVP 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.”

Tang said that the companies will multiply leading-edge product development and design capabilities, aiming to achieve closer technology exchange and collaboration to speed 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,” he added.

Developing next-gen automotive power management

The companies said there are three phases of development for next-generation automotive power solutions collaboration.

TI said that phase one focuses on Delta’s development of a lighter-weight, cost-effective 11 kW onboard charger, using TI’s latest C2000 real-time microcontrollers and TI’s proprietary active electromagnetic interference filter products. The companies said they 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 said they 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, representing the strictest automotive safety requirements. The companies said that highly integrated automotive isolated gate drivers will further enhance the power density of onboard chargers, while minimizing overall solution size.

In phase three, the companies said they 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,” Luke Lee, president of Taiwan, Japan, Korea and South Asia, Texas Instruments, said in a statement. “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.”
