Application of DC-DC converter in new energy vehicles

With the rapid popularization of new energy vehicles, more and more people begin to pay attention to the core components such as pow-

er batteries and motors, but few people pay attention to the DC-DC converter hidden inside the car body. This seemingly unremarkable d-

evice is a bridge connecting the high-voltage power battery and the low-voltage electrical appliances of the whole vehicle, which is called 

the "invisible heart" of new energy vehicles.

Traditional fuel vehicles rely on engines to drive generators to supply power to low-voltage devices such as lights, instrument panels, car 

entertainment, and window motors. The new energy vehicle has no engine and generator, and the power battery outputs 200V~800V 

high-voltage direct current, which cannot be directly used for 12V low-voltage equipment. DC-DC converter is born to solve this problem, 

which replaces the role of traditional generator, converts high-voltage DC into 12V low-voltage DC stably, and provides continuous power 

for the low-voltage system of the whole vehicle.

The vehicle-mounted DC-DC converter follows the working flow of "DC-high frequency AC-transformer isolation-DC". Firstly, the high-

voltage DC is converted into high-frequency AC by inverter circuit, and then the voltage is reduced and isolated by high-frequency tra-

nsformer. Finally, the stable 12V DC is output by rectifier and filter circuit. A new generation of products equipped with LLC resonance 

and synchronous rectification technology, the conversion efficiency can reach more than 96%, and at the same time, it has multiple p-

rotection functions such as overvoltage, overcurrent, overheating and short circuit to ensure the safety of the whole vehicle.

In addition to the field of new energy vehicles, DC-DC converters are also widely used in communication base stations, industrial cont-

rol, photovoltaic energy storage and other industries. Different scenarios have different requirements for voltage level, power size and 

protection level, so it is necessary to select suitable products.

Baoweite has been deeply involved in DC converter technology for many years, and can provide a full range of DC-DC converter prod-

ucts, covering various voltage levels such as 48V, 110V and 220V, and the power can be selected from 100W to 10KW. The products are 

designed in industrial grade, with stable operation and high conversion efficiency, which are widely adapted to the power supply needs 

of new energy supporting, communication, electric power, industry and other fields, and provide reliable high-low voltage conversion 

solutions for various types of equipment.
