Why Nanocrystalline for EV Charging?
EV charging systems require high-frequency operation for compact design and fast charging speeds. Nanocrystalline cores excel in these demanding applications.
High Frequency Performance
Excellent performance at 20-100kHz switching frequencies used in modern EV chargers. Lower losses than ferrite cores at these frequencies.
High Power Density
Higher saturation flux density (1.2-1.3T) enables smaller transformer size for the same power rating, critical for compact EV charging stations.
Thermal Stability
Stable performance from -40°C to +130°C, essential for outdoor EV charging infrastructure and automotive applications.
EV Charger Transformer Core Requirements
EV charging systems demand transformer cores that can handle high-frequency switching (20-100kHz) while maintaining high efficiency and compact size. Key requirements include galvanic isolation for safety, low leakage inductance for fast transient response, and thermal stability for outdoor installations.
Our nanocrystalline transformer cores for EV chargers excel in these applications due to their superior saturation flux density (1.2-1.3T), enabling smaller transformer designs compared to ferrite cores. The low core losses at switching frequencies improve overall system efficiency, critical for fast charging applications. For EMI suppression, consider our EMI filter cores and CT cores for current sensing.
