Application characteristics of DC-DC converters in new energy vehicles
DC-DC converters as an important part of the power system of electric vehicles

We all know that DC-DC converter is a DC conversion device that converts a DC base power source into other voltage types. Moreover, in the electronic systems or equipment of electric vehicles, the DC bus in the system cannot meet the high requirements of various performance and types of components for the voltage level and stability of the DC power supply. Therefore, various DC-DC converters must be used to convert the widely varying DC voltage into stable DC power to meet the various requirements of the electronic system.

As an important part of the power system of electric vehicles, DC-DC converters convert the direct current energy of high-voltage batteries into low voltage to supply power to the low-voltage systems in the vehicle. Their main function is to provide the necessary electricity for the power steering system, air conditioning, and other auxiliary equipment. Compared to traditional fuel vehicles, DC-DC converters for new energy vehicles have the following characteristics


1. High voltage input: High voltage batteries in new energy vehicles typically operate in the voltage range of tens to hundreds of volts, so DC-DC converters need to be able to accept and process high voltage inputs to achieve energy conversion.

2. High power processing capability: DC-DC converters for new energy vehicles need to have high power processing capabilities to achieve efficient and stable DC energy conversion, in order to meet the electrical energy needs of the vehicle's low-voltage system. Multiple components such as auxiliary electrical appliances, power steering, in car entertainment, and in car communication are all low-voltage systems. In order to ensure their normal operation, DC-DC converters play an important role in them.

3. High conversion efficiency: In order to improve the efficiency of vehicles, DC-DC converters for new energy vehicles have high conversion efficiency, which can reduce energy loss during the conversion process and improve energy utilization.


4. Extend battery life: DC-DC converters are also designed to extend battery life. Through its efficient energy conversion, management, and control regulation capabilities, it avoids inappropriate operations during battery charging and discharging processes and reduces damage to the battery.


5. Accurate voltage regulation capability: The low-voltage system of new energy vehicles needs to maintain stable voltage supply to ensure the normal operation of various systems. DC-DC converters need to have precise voltage regulation capability to achieve high-precision output voltage stability.


          The DC-DC converter of new energy vehicles has special requirements in high-voltage input, high-power processing, high efficiency, battery life, and precise regulation to meet the electrical energy conversion and power supply requirements of the low-voltage system of electric vehicles.
