Professional Provision of Magnetic Core Component Solutions
New Energy Vehicles
In new energy vehicles, the power electronic system is responsible for energy conversion, distribution and control.
As core magnetic components, transformers and inductors are widely used in both the high-voltage and low-voltage systems of the entire vehicle, directly affecting the vehicle’s safety, efficiency and reliability.
Core Requirements of New Energy Vehicles for Magnetic Components
The power supply systems of new energy vehicles usually have the following characteristics:
- High-voltage platforms (400V / 800V)
- High-frequency power supply topologies (SiC / GaN)
- Extremely high requirements for safety isolation
- Strict requirements for efficiency, temperature rise and EMI
- Long-term stable operation (automotive-grade reliability)
Against this backdrop, transformers and inductors have become indispensable key components.
Applications of Transformers in New Energy Vehicles
Main Application Scenarios
- On-Board Chargers (OBC)
- High-voltage to Low-voltage DC/DC Converters
- Isolated Auxiliary Power Supplies
Core Functions
- Voltage Conversion: Meet the voltage requirements of different systems
- Electrical Isolation: Ensure the safety of personnel and the entire vehicle system
- High-frequency Design: Reduce size and improve power density
In OBC and DC/DC systems, isolated transformers are the core components that achieve safe and efficient energy conversion.
Applications of Inductors in New Energy Vehicles
Main Application Scenarios
- PFC Power Factor Correction Circuits
- DC/DC Energy Storage and Filtering
- Electric Drive System (Inverter) Filtering
- EMI Common-mode / Differential-mode Filtering
Core Functions
- Energy Storage and Release
- Smooth Current and Reduce Ripple
- Suppress High-frequency Interference and Improve System Stability
Inductors are used in large quantities and widely distributed in new energy vehicles, serving as an important foundation for ensuring the power quality of the entire vehicle.
Collaborative Applications in Typical Systems
In practical applications, transformers and inductors usually work in synergy:
- Transformers are responsible for isolation and voltage conversion
- Inductors are responsible for energy storage, filtering and current control
The two together determine the system efficiency, noise level and reliability.
This combination is widely used in systems such as OBC, DC/DC, inverters and auxiliary power supplies.
