Do you know how many automotive transformers are in an intelligent vehicle? In an intelligent vehicle, the number of automotive transformers usually reaches dozens or even more! With the continuous development of the automotive industry, especially driven by the digital transformation in the automotive industry, the electrification and intelligence levels of vehicles are increasing day by day. Among them, automotive transformers, as key electronic components, play an indispensable role. More and more electronic systems require stable voltage conversion and signal isolation, which has significantly increased the quantity and variety of automotive transformers.
This article will focus on automotive transformers, delving into their applications in intelligent vehicles and their impact on the driving experience.
Where Are Automotive Transformers Used in Vehicles?
To understand the working principle of an automotive transformer, one first needs to master some basic electrical concepts.
- Voltage refers to the potential difference between two points. In a transformer, it is adjusted to meet the requirements of different applications.
- Current is the flow of electric charge through a conductor. The design of a transformer ensures that the current is compatible with the required voltage level.
- Resistance is the opposition of a material to the flow of electric current. An efficient transformer design aims to minimize resistance to reduce energy loss.
The core working principle of an automotive transformer is to transfer electrical energy between circuits through electromagnetic induction while providing electrical isolation. According to Faraday’s Law, a changing magnetic field within a coil induces an electromotive force (EMF). In a transformer, an alternating current in the primary winding generates a changing magnetic field, which forms a magnetic flux in the transformer core and, in turn, induces a voltage in the secondary winding. The turns ratio of the primary and secondary windings determines the voltage conversion ratio.
In practical applications, there are various types of automotive transformers: step-up transformers, step-down transformers, isolation transformers, etc.

The OBC is responsible for converting the external power supply into the appropriate voltage and current for battery charging. The automotive transformer plays the role of voltage conversion and electrical isolation in the OBC, ensuring the safety and efficiency of the charging process.
2. DC/DC Converter
The DC/DC converter converts the high-voltage battery voltage into a low-voltage one to supply power to on-board electronic devices. A high-quality automotive transformer can improve conversion efficiency and reduce energy loss.
3. Drive Motor System
The drive motor system is the core of new energy vehicles and is responsible for power output. The automotive transformer is used in the motor control circuit to ensure the accurate conversion of current and the isolation of signals, improving the motor’s response speed and control accuracy, thus enhancing the vehicle’s power performance and driving experience.
4. Automotive Network and Communication System
With the development of intelligent connected technology, the in-vehicle high-speed data transmission system has become particularly important. The automotive LAN transformer provides signal isolation and anti-interference capabilities for the in-vehicle Ethernet and communication systems, ensuring the stability and security of in-vehicle information transmission. It is a key guarantee for the intelligent driving experience.
5. Battery Management System (BMS)
The BMS is responsible for monitoring the battery status and preventing overcharging, over-discharging, and overheating. The automotive transformer is used for signal isolation and voltage conversion in the BMS to ensure the accuracy of data transmission and the safety of the system, thereby improving battery life and vehicle safety.
