XV3300, a 3.3kW battery charger powers the vehicle's auxiliary loads. These include ignition, power steering, ABS, lamps, infotainment, and air conditioning.

Energy Efficient Converters and Usage of Advanced Material to Trend in Global Market

The latest technological advancements in global automotive DC-DC converter drive the market growth. These technology-based upgrades involve boosting the power conversion rate while delivering power supply as required. EV component manufacturers are shifting from silicon-based solutions to power-semiconductor technologies to utilize wide bandgap (WBG) materials. These involve silicon carbide (SiC) and gallium nitride (GaN). While SiC enhances the power density of an electronic system, it also lowers the overall weight, size, and cost. Hence, SiC is being used in converters at a strict size. Furthermore, GaN boosts the overall efficiency during power conversion. Integration of these elements makes the converters fast, efficient, and highly functional. Hence, it is adopted as a silicon substitute in high-efficiency voltage converters.

For instance, in September 2023, Vanner Inc. launched serial production of a new DC-DC converter with SiC (Silicon Carbide) technology. The company has launched this new range of DC-DC converters with silicon carbine-solid state switching, delivering improved electrical efficiency.

Higher Adoption of Hybrid and Electric Vehicles to Transform the Market

The rising fuel prices, increasing EV range and enhanced efficiency increase demand for EVs and HEVs. Government authorities are also trying to limit vehicular emission to the minimum and are subsidizing and promoting the usage of electric vehicles. These factors positively impact the overall electric vehicle industry and the component markets. With new EV technologies developing, the power chargers and converters are also becoming highly efficient with very little power consumption. Some developments in DC-DC converters include a wider input range, ultra-low power consumption, and low maintenance. These converters offer functions like remote and battery-free operations, asset monitoring, and IoT integration.

For instance, in January 2024, Onsemi (ON Semiconductor Corporation) introduced the DC SiC power modules to speed up EV charging. It includes a high-power one-way DC-DC converter with the new SiC PIMs. The converter reduces wasted energy and increases overall vehicle charging efficiency.

Government Supporting EV Manufacturers to Further Drive the Market Growth

The government's focus on transitioning transportation measures allows it to invest and collaborate with private companies. Public-private partnerships (PPP) between the government and EV component manufacturers also help drive market growth. Furthermore, the government's subsidies, tax cuts, and technological support are also garnering industrial expansion. New companies with advanced DC-DC converters that support faster charging and lower energy waste benefit from these government schemes. The increased production line and strong supply chain are some outcomes of government aid to the respected industry.

In February 2023, the White House announced the implementation of President Biden's Build America, buy America requirements, which will encourage companies to invest domestically in EV charging component manufacturing, putting American workers and businesses ahead of the competition and ahead of the world in a critical sector while providing a sensible transitional period for companies transitioning to onshore, complex supply chains.

Higher Efficiency and Safety Dynamics put Isolated DC-DC Converter on the Top

Based on power supply, isolated DC-DC converters perform significantly better than non-isolated converters. Better power supply, streamlined delivery, and multifunctional application make isolated DC-DC converters a better option for electric vehicles. Electric vehicles include different auxiliary loads that need to be powered with a specific power supply. The converter also provides stability and independence to the input voltage. The converter also enhances safety and limits the risk of electric shocks while protecting the vehicle's crucial electronics. Furthermore, popular electric vehicle manufacturers are adopting isolated DC-DC converters for their multifunctional applications.

For instance, in November 2023, CUI Inc, a Bel group company introduced a series of isolated DC-DC converters named PGNM-S and PGNP-S, specialized for EV charging and industrial electronics applications. The series offers 6000 VAC isolation with 1:1 input voltage and is EN/BS EN / UL 60601-1 certified.

Asia-Pacific Dominates Automotive DC-DC Converter Market

Electric vehicle manufacturing along with EV sales are growing in the Asia-Pacific region. While China expands its EV manufacturing space, Indian automotive giants upgrade their vehicles with hybrid and electric technology. The rising economic activities in India and China are increasing the purchasing power and hence higher EV adoption can be witnessed in the region. New startups and EV component industries are also building the base for the expansion of the overall EV industry. Supportive government policies including subsidies and financial incentives are also helping the market growth in the region. The authorities also help the native brands in their research and development programs.

For instance, in October 2023, Toyota Motor Corporation announced the launch of its bZ4X BEV in India. The launch is expected to be in 2024 with the advanced DC-DC converter. By combining the on-board charger with the necessary DC-DC converter for BEV. It is 23% smaller and 17% lighter than mounting the two separately.

Future Market Scenario (2024 – 2031F)
