Market Dynamics

Introduction

DC-DC converters play a critical role in electric vehicles (EVs) by stepping down high-voltage DC power from the main traction battery (typically 400V or 800V) to lower voltages such as 12V or 48V. This low-voltage power is essential for operating auxiliary systems, including lighting, infotainment, wipers, power steering, and control units, ensuring a stable and efficient power supply without requiring a separate auxiliary battery charger. The converter allows seamless integration and operation of all vehicle electronics from a single power source.

Modern DC-DC converters go beyond basic voltage regulation; they are integral to energy efficiency and power management across the entire vehicle electrical architecture. With EV platforms becoming increasingly electronically sophisticated, the demand for compact, thermally managed, and high-power-density DC-DC converters is rising. These converters must fit within space-constrained environments while delivering high performance and reliability, reinforcing their growing importance in next-generation electric vehicles.

Key Trends:

One of the most significant trends in the EV DC-DC converter market is the emergence of high-frequency, compact form factor converters enabled by wide bandgap (WBG) materials such as Gallium Nitride (GaN) and Silicon Carbide (SiC). These advanced semiconductors offer superior efficiency, faster switching, and enhanced thermal performance, making them ideal for space-constrained and high-performance EV architectures. Additionally, there is a growing interest in multi-output and inverting DC-DC converters, which allow energy sharing between various vehicle subsystems. This improves system flexibility and enables greater energy optimization, supporting the evolution of more integrated and intelligent EV power architectures.

Market Drivers:

The EV DC-DC converter market is being driven by several key factors:

• Rising global adoption of electric vehicles (EVs), driven by strict environmental regulations and government incentives.
• Increasing vehicle electrical complexity with multiple ECUs, infotainment, safety systems, and ADAS, all of which require stable low-voltage DC power.
• The trend toward high-voltage (800V) EV architectures for fast charging requires more advanced DC-DC converters.
• Increasing demand for high power density, compactness, and thermal efficiency to optimize space and performance.
• Growing demand for bidirectional power flow applications like vehicle-to-grid (V2G) and vehicle-to-home (V2H) is encouraging the development of bidirectional DC-DC converters that can manage power flow in both directions.
• Rising adoption of integrated DC-DC converter solutions to reduce the number of components, weight, and overall cost, further driving market innovations.

Recent Market JVs and Acquisitions:

A considerable number of strategic alliances, including M&As, JVs, etc., have been performed over the past few years:

• In October 2020, BorgWarner Inc. acquired Delphi Technologies to enhance its position in the electric vehicle (EV) market and broaden its electrification portfolio, including DC-DC converters, inverters, and onboard charging systems.

In March 2023, Infineon Technologies AG and Delta Electronics Inc. expanded their long-term cooperation from industrial to automotive applications. The agreement covers high-voltage and low-voltage discretes and modules and microcontrollers for use in EV drivetrain applications such as traction inverters, DC-DC converters, and onboard chargers.

Market Segments' Analysis

Market Segments' Analysis

“Isolated DC-DC converters are likely to remain dominant and a faster-growing topology type during the forecast period.”

There are two topology types in DC-DC converters: isolated DC-DC converters and non-isolated DC-DC converters. Isolated DC-DC converters, owing to their enhanced safety and reliable performance, are projected to remain the dominant topology in the EV DC-DC converter market over the coming years. By providing galvanic isolation between the high-voltage battery and low-voltage systems, isolated DC-DC converters ensure the protection of sensitive electronic components and enhance passenger safety—a critical requirement in modern electric vehicles, particularly in high-voltage and commercial platforms.

With the increasing shift toward 400V and 800V EV architectures, the demand for isolated DC-DC converters is growing. These systems not only enable effective power management across various subsystems but also play a key role in preventing electrical faults. Their ability to support complex features like ADAS and infotainment with stable, interference-free power delivery makes them the preferred choice across multiple EV segments.

By Propulsion Type

“Currently, HEV holds the largest share of the market, whereas BEV is likely to experience the fastest growth in the coming years.”

There are two propulsion types in DC-DC converters, BEV and HEV.HEVs have a larger installed base and widespread adoption, especially in markets where full EV infrastructure is still developing. They require continuous and efficient power conversion between high-voltage and low-voltage systems to support auxiliary loads during frequent engine start-stop cycles and regenerative braking. Additionally, the higher sales volume of HEVs globally, majorly in regions like India, China, and Japan, pushes their leading position in the current EV DC-DC converter market.

BEVs (battery electric vehicles) are the faster-growing propulsion type of the market, majorly driven by the global shift toward fully electric transportation. This trend is fueled by stringent emissions regulations, government incentives, and rising environmental awareness. The demand for highly reliable and efficient DC-DC converters continues to accelerate in line with the growing adoption of BEVs.

By Vehicle Type

“LV is projected to remain the dominant and fastest-growing vehicle type of the EV DC-DC converter market in the coming years.”

The market is segmented into LV and M&HCV. Representing the largest share of global electric vehicle sales, LV includes passenger cars and compact EVs, which are central to everyday urban mobility. These vehicles require reliable and efficient DC-DC converters to support essential low-voltage systems such as lighting, infotainment, and safety electronics, making them a critical application area for converter technologies.

As more people look for affordable, efficient, and eco-friendly transportation, light-duty vehicles (LVs) are expected to drive strong growth in the EV DC-DC converter market. The growing EV charging network and supportive government policies are also helping more people choose electric LVs, making them the most common type of EV on the road.

By Power Rating Type

“> 5kW is expected to remain the dominant power rating type of the market during the forecast period.”

There are three power rating types in DC-DC converters: < 3kW, 3kW to 5kW, and > 5kW. > 5 kW power converters are critical for larger battery-powered vehicles such as battery electric vehicles (BEVs) and commercial electronics vehicles, which need effective and reliable power management to power up multiple high-power subsystems. These converters are essential in delivering power from the main battery across to several auxiliary systems, such as HVAC, infotainment, and the charging system.

The increasing trend in the need for longer-range EVs, combined with development in battery technology, creates a need for high-power DC-DC converters to support optimum performance and increased charging times.

Regional Analysis

“The Asia-Pacific is expected to remain the largest market for EV DC-DC converters during the forecast period.”

In terms of region, the market is segmented into North America, Europe, Asia-Pacific, and the Rest of the World. During the forecast period, it is expected that Asia-Pacific will remain the leading region in the EV DC-DC converter market. This is mainly attributed to the higher adoption of electric vehicles in key countries, such as China, India, Japan, and South Korea, where passionate government policies, incentives, and investments are catalysing the transformation to electric mobility. The area also has some of the biggest EV manufacturers and a tried and tested supply chain of EV components: power electronics such as DC-DC converters. Furthermore, Asia-Pacific is the epicenter of technological innovations as well as a manufacturer and hence an important player in the development and manufacture of high-efficiency power conversion systems.
