Market Dynamics
Increasing R&D Investments to Include Dc-Dc Converters in Commercial Vehicles
Automotive OEMs are using innovative technologies in their vehicle offerings to improve fuel economy as stricter pollution standards are increasingly adopted. Electric drivetrains for medium and heavy commercial vehicles (M&HCVs) have been created as a result of this trend. To provide greater efficiency, the electric drivetrain requires the inclusion of a DC-DC converter. Component producers have upgraded their product lines in response to the rise in commercial vehicle sales.
Additionally, a 48V to 12V DC-DC converter from Prodrive that complies with the ISO/DIS 21780 standard for 48V automotive systems has been introduced. The converter comes in a variety of power choices ranging from 400W to 2.2kW and may be customized to fit automotive networks including can and FlexRay.
Furthermore, the logistics and municipal industries have experienced a major increase in demand for pick-up trucks because of rising freight and logistics activity. Particularly in Europe and North America, the market for personal electric pickup trucks has recently seen considerable growth. In context essentially, manufacturers like Ford, General Motors and Volkswagen have intensified their attention on electric production vehicles. In the upcoming years, a number of new businesses and startups have declared their intent to produce hybrid or all-electric pickup truck models.
Increasing Consumption of Energy-Efficient Electric Vehicles
The plans and initiatives of various governments, including those of India, China, France, Germany, U.S. and others, which encourage the use of environmentally friendly vehicles and contribute to the development of infrastructure for these vehicles, are driving up demand for electric vehicles. As a result, the market for these vehicles is expanding significantly.
For instance, the government of France has implemented an environmental bonus to encourage models with low CO2 emissions; the government of Germany offers grants of USD 2,370 for BEVs and FCEVs and $1,780 for PHEVs; and the government of China offers subsidies for the electrification of vehicles. Electric vehicle DC-DC converters are employed to modify the voltage levels from connected batteries in accordance with the power demands of various in-car systems.
Regulation Adhesion and Safety Demands For DC-DC Converters
To prevent harm or damage to people or property largely as a result of potential risks such electric shock, energy hazards, radiation hazards and chemical hazards, several international and local rules and standards have been created for DC-DC converters. Manufacturers of DC-DC converters are required to follow these rules and specifications, which cover a range of insulation types such as functional, primary, supplemental, double and reinforced insulation.
As these regulations limit manufacturers' growth as they differ from country to country leading to hampering the product’s growth. It may require a specialist to understand these standards given that they are so technically advanced. It gets more difficult for DC-DC converters to kee up with these requirements as they experience continuous development and modification thus acting as a major restraint for market growth.
Market Segment Analysis
The global automotive DC-DC converters market is segmented based on product, propulsion, input voltage, output voltage, output power, vehicle, application and region.
Rising Demand for Isolated DC-DC Converters in Renewable Energy Systems
The isolated DC-DC converters segment holds a major share of around 45.4% in the global automotive DC-DC converters market and countries like the U.S., Canada, Germany and the UK have shown the highest growth in the market. Isolated DC-DC converters are frequently used in this industry as essential components for power conversion because of the growing demand for secure and effective renewable energy systems.
The propulsion systems of electric and hybrid cars, which need high-frequency transformers to act as a barrier to high-frequency voltage, are another important factor driving the demand for isolated DC-DC converters. For automotive, e-mobility and battery applications, Calex introduced the Ruggedized 3kW Bi-Directional DC-DC Converter. In a similar vein, Artesyn introduced a 10-Watt Isolated DC-DC Converter in 2019 for a variety of uses, including automotive.
