PQ Series New Energy High-power Transformer Charging High-Frequency Transformer
The PQ series new energy high-power charging high-frequency transformer is a high-performance magnetic component specifically engineered for electric vehicle on-board chargers (OBCs), charging stations, and high-power industrial power sources. Featuring optimized PQ magnetic core geometry that combines large window area with high magnetic core cross-sectional area, this series delivers powerful power processing capability in a compact form factor.
Core Advantages
Power range from 50W to 6kW+ with compact size design
Low-loss ferrite materials (PC44, 3C95, N87) for stable high-frequency operation
Operating frequency range: 20kHz to 500kHz
Conversion efficiency exceeding 95%
Compact structure with low magnetic leakage and strong anti-interference performance
Supports multiple topologies including flyback, forward, LLC resonance, and full bridge
Customizable winding turns ratio, insulation level (B/F/H), and pin configuration
High power density with excellent thermal management
Reliable safety isolation with withstand voltage up to 3.75kV-4kV
Applications
This transformer serves as a core component in electric vehicle onboard chargers (OBC), DC fast charging stations, and auxiliary DC-DC converters. It is widely used in renewable energy systems including photovoltaic inverters, wind power converters, and energy storage systems. Industrial applications encompass communication base stations, uninterruptible power supplies (UPS), server power supplies, industrial control equipment, rail transit auxiliary power systems, smart grid devices, and high-end consumer electronics such as fast chargers for power tools and drones.
0.5 VA up to 6 kW+, depending on core size (e.g., PQ20: 50W max; PQ35/35: 350W; PQ50: 1000W+)
Efficiency
Up to 95% to 99%
Operating Temperature
-40°C to +125°C (typical); some models up to +180°C
Storage Temperature
-40°C to +100°C (typical)
Dielectric Strength (Hipot)
1.5 kV to 4.0 kV AC, depending on insulation requirements
Insulation Resistance
100 MΩ min. at DC500V
Inductance Tolerance
Typically ±8% to ±10% at 1 kHz/0.25V or 1 kHz/1V
DC Resistance (DCR)
As low as 4 mΩ to 780 mΩ (varies by winding and model)
Leakage Inductance
Typically 4.0 µH Max. to 6.0 µH Max.
Core Geometry
Optimized PQ shape for high power density, low leakage flux, and good thermal performance
