AUTOMOTIVE DC DC CONVERTER MARKET
KEY FINDINGS
- At present 150+ BEVs are under development globally ,which will be launched by 2021-2022, and the long term supplier contracts for DC-DC converter are still being worked upon.
- The DC-DC converter market in US will be driven by BEVs, which will account for 53% share in 2019 and 48% share in 2025, 2-2.5kW converters will make up for a significant chunk of demand.
- In passenger vehicle segment, Tesla vehicles have the most powerful DC-DC converter and on-board chargers at 2.5kW and 7.7kW-11.5kW respectively. The compact Chinese BEVs have a low power converter, but their share has been gradually shrinking as of Q3-2019.
- In China, which accounts for 50% of global EV sales, the automotive DC-DC converter market is heavily skewed towards low powered compacts.Vehicles with <25kWh batteries and <2kW DC-DC converters comprised a significant share of EV sales in China in 2018. But, as of Q3-2020 the market structure has significantly changed.
- Silicon Carbide (SiC) power semiconductor for automotive applications, there are new opportunities to further optimize and improve performance of VVC, e.g. lower power loss, smaller size, and lighter weight, comparing to use traditional Silicon (Si) IGBT and diode.
- Reduction of magnetic flux leakage is primary concern. The application of the proposed coupled inductors has increased the continuous power density of the DC-DC converter approximately 2-fold in comparison with the conventional unit employed in previous gen vehicles.
INTRODUCTION
As fossil fuel powered engines get closer to prohibition, many OEMs are looking up to vehicle electrification as a saviour. Battery powered electric vehicles will not become mainstream unless battery costs come down to <$100/kWh and fast charging infrastructure becomes a common place. Now, that leaves manufacturers with a bridge gap or a “hybrid” solution.
A 48V Mild-hybrid/Plug-in hybrid architecture can result in 10%-16% increase in fuel economy at an added cost of 6%-12% of vehicle. In any case, hybridization warrants a DC-DC converter in a vehicle.
MARKET DYNAMICS
The ousting of Diesel as a fuel of choice has been driving the market in Europe. The onset of WLTP cycle in Europe has delivered almost a deadly blow to the diesel. Share of Diesels in new car registration has gone below 35% in top 5 EU markets in Jan-Sep 2019 and we expect it to reach <25% by 2021.Mild hybrids and Plug in hybrids will be the biggest benefactors of this market shift, ultimately driving the automotive DC-DC converter market.
The on-board DC-DC converter has undergone many improvements in recent past like optimization of control output, weight and size reduction, and improved NVH (noise vibration and harshness). When Hitachi launched its 3rd gen DC-DC converter, back in 2014 it was 40% compact and 5% more efficient than the one it replaced. Similarly, Delphi launched industry first combined inverter and DC/DC converter in China in July 2018.
So, far the efficiency of power electronics for automotive applications has been limited due to use of Silicon. Going forward, we expect new materials like SiC (Silicon Carbide) to gain more traction, as it has nearly 10 times higher electric field strength and 3 times higher thermal conductivity.

MARKET SEGMENTATION
MARKET SIZE AND FORECAST
By 2025, xEVs will account for 10% of total vehicular production, as compared to ~5% in Jan-Sep 2019.48V Mild hybrids will account for a major chunk of those vehicles. China and Japan cumulatively accounted for more than 40% of global DC-DC converter market in Jan-Sep 2019.The Chinese EV sales quota of 8% in 2019, 10% in 2020 and 20% by 2025 has spurred investment in China by many foreign tier-1 electronics manufacturers. But, subsidy reduction in July 2019 has brought down EV sales in China by more than 30% in Q3-2019.
Diesel Mild- hybrids are the latest application for automotive DC-DC converters. Kia, Audi, FCA group have announced plans to launch multiple Diesel mild-hybrid models in 2019.48V also allows for electrification of other ancillaries like electric HVAC compressor, electric coolant pumps, electric turbochargers, electronic air suspension etc.
China is the biggest EV DC-DC converter market at present by volume and it is majorly comprised of BEVs, which is a very sharp contrast as compared to US, Europe or even Asia Excluding China. Japan had more than 25% share of HEVs in Jan-Sep 2019. We expect many long range BEV models with connected and semi-autonomous features to be introduced in the Chinese market post 2021 from all mainstream domestic brands like Geely , JAC, Great Wall Motors, SAIC etc ,many of them are under development right now.
In Europe,Ford(6-7% market share) is aggressively looking at electrification for its best-selling cars as well as vans. It may partially exit the passenger car scene 4-5 years later and exclusively focus on high margin van business.Among mass segment brands, VW ,Skoda and Seat will rely on MEB platform and low cost BEVs.
In terms of volume, the xEV DC-DC converter market size was estimated at 4.8 Million units in 2019, growing at 23% CAGR to 2025.

COMPETITIVE LANDSCAPE
The DC-DC converter market has more than 10 vendors and the top 9 listed below accounted for a major chunk of the market in 2018. As this power electronics component requires high expertise and robust validation, the barriers to entry are significantly high. Thus, we have only the established tier-1s supplying this component to the OEMs. Toyota Industries, Continental AG, Delta Electronics and Valeo are the leading players in the automotive DC-DC converter market globally.
Most of the suppliers have launched new and improved products to improve their positioning in the market. Some of the suppliers offer DC converters as a standalone sub-component, whereas some offer it as a part of complete 48V mild hybrid system. In terms of inorganic growth, there have been very few partnerships and almost none acquisitions in the automotive DC-DC converter market.
To capitalize on growing DC-DC converter market volume, suppliers have devised diversified strategies. Eaton created a new E-mobility business in June 2018, to supply power electronics to passenger and commercial vehicle market. Continental partnered with China based battery manufacturer CITC in March 2018 to supply complete 48V mild hybrid system.
