Will air-cooled HV DCDC converters change the EV game?
Exploring the potential benefits of air-cooled HV DCDC converters for the future of electric vehicles
HV DCDC converters are key in powering infotainment and lighting in electric vehicles. Liquid cooling renders them efficient and reliable, but is more complex and costly than air cooling. WBG devices like SiC and GaN offer superior performance and efficiency as compared to silicon-based devices. GaN-based HV DCDC converters help reduce cooling requirements, increase power density, reduce size and weight, and improve overall efficiency. GaN-based HV DCDC converters have the potential to be a game changer for the EV market by driving innovation and leading the way in developing new power solutions for the future of mobility.

As electric powertrain architectures continue to evolve, the role of HV DCDC converters in powering vehicle systems is becoming increasingly important. HV-DC-DC converters are responsible for converting the high voltage of the battery to the lower voltage required to power vehicle systems such as infotainment, air conditioning and lighting. With the increasing electrification of vehicle systems, multiple voltage levels are being introduced to power different components of the vehicle, making HV-DC-DC converters a critical component in the EV ecosystem.
The integration of HV DCDC converters into an EV is critical to vehicle cost, scalability and range. The design of HV DCDC converters must be optimised to ensure that the power electronics are efficient and reliable, while also being cost effective, scalable and space efficient. Currently, most HV DCDC converters are liquid cooled due to the high power density and heat generated by the power electronics. Liquid cooling provides an efficient, high-capacity cooling solution that can maintain stable operating temperatures over a wide range of operating conditions. ?
However, liquid cooled HV DCDC converters have several limitations. For example, liquid cooling systems are more complex and expensive than air cooling systems, which can increase production costs and reduce scalability. In addition, liquid cooling systems require more maintenance and are more susceptible to leaks and other failures. Air-cooled HV DCDC converters have the potential to offer several advantages for EV applications. Air-cooled systems are simpler and less expensive than liquid-cooled systems, making them more scalable and cost-effective. Air-cooled systems also require less maintenance. Air-cooled HV DCDC converters also have several limitations that need to be considered. The main limitation is the lower cooling capacity of air-cooled systems compared to liquid-cooled systems. In addition, air cooling systems are less effective at maintaining stable operating temperatures over a wide range of operating conditions, which can affect the efficiency and reliability of the converter.
Semiconductor technologies play a crucial role in determining the efficiency and performance of HV-DC/DC converters, making them a critical component in the EV ecosystem.
The two main semiconductor technologies used in HV-DC/DC converters are silicon-based devices and wide-bandgap (WBG) devices such as silicon carbide (SiC) and gallium nitride (GaN). Silicon-based devices are widely used in HV-DCDC converters because of their low cost and high thermal conductivity. However, SiC and GaN WBG devices are gaining popularity due to their superior performance and efficiency.
WBG devices have several advantages over traditional silicon-based devices. They have a higher breakdown voltage and can operate at higher temperatures, enabling higher power density and efficiency. WBG devices also have a faster switching speed, resulting in lower switching losses, and they have lower conduction losses due to their lower on-state resistance.
GaN-based HV DCDC converters have the potential to overcome some of the limitations of air-cooled designs. GaN-based devices have several advantages over traditional silicon-based devices, including lower conduction and switching losses, higher breakdown voltage and faster switching speed. These advantages can result in higher efficiency, power density and performance of the HV DCDC converter, making it well suited for air-cooled designs. The improved efficiency of GaN-based HV DCDC converters can help to reduce the cooling requirements of the converter as less heat is generated. This can help overcome the limitations of air-cooling systems, which have a lower cooling capacity than liquid-cooling systems. By reducing cooling requirements, GaN-based converters can potentially increase the power density of the converter, reduce the size and weight of the converter, and improve the overall efficiency of the EV.
Semiconductor technologies play a crucial role in determining the efficiency and performance of HV-DCDC converters, making them a critical component in the EV ecosystem. The impact of these semiconductor technologies on the vehicle is significant. The higher efficiency of HV-DCDC converters with WBG devices results in lower energy consumption, which translates into longer range and improved performance. In addition, the higher power density of WBG devices enables more compact and lightweight HV-DCDC converters, resulting in a more efficient and space-saving design. While more research and development is needed, GaN-based HV DCDC converters have the potential to be a game changer for the EV market, helping to drive innovation and lead the way in developing new power solutions for the future of mobility.
