Customized High Frequency PQ50 Low Profile Planar Transformer High Efficiency PCB Winding Transformer for Renewable Energy
Product Overview
The PQ50 Series Planar Transformer is a high-capacity magnetic component specifically designed for heavy-duty power conversion systems ranging from 2kW to over 6kW. By combining the optimized geometry of the PQ (Power Quality) core with advanced multi-layer PCB or copper busbar winding technology, the PQ50 stands as a premier solution for high-frequency DC-DC converters and On-Board Chargers (OBC). It is engineered to replace traditional wire-wound transformers in environments where extreme efficiency, low profile, and superior thermal management are the primary design drivers.

Product Features
Optimized PQ50 Geometry: The PQ core design is mathematically optimized to provide the best possible ratio of core volume to surface area, ensuring a massive Effective Cross-Sectional Area (Ae≈328 mm²). This allows for high energy throughput with minimal core losses.
Planar Winding Architecture: Utilizes multi-layer PCB traces or heavy-gauge copper plates, ensuring a low-profile height (typically under 25mm) while maintaining exceptionally high current-carrying capacity.
High-Frequency Capability: Optimized for switching frequencies between 100kHz and 500kHz, making it a perfect match for high-speed Silicon Carbide (SiC) and Gallium Nitride (GaN) power stages.
Safety & Isolation: Features reinforced insulation systems capable of withstanding isolation voltages up to 4kV AC, ensuring compliance with global safety standards for industrial and automotive applications.
Technical FAQ
How does the PQ50's specific Ae value (328 mm²) impact the magnetic flux density (Bmax) and overall efficiency in a 5kW LLC resonant converter?
The large Ae of the PQ50 is its greatest technical asset. In a 5kW LLC converter, a larger Ae allows the transformer to operate at a lower Magnetic Flux Density (Bmax) for a given number of turns. This significantly reduces Core Losses (Hysteresis and Eddy current losses), which are proportional to the flux density. By keeping the core further from the saturation point, the PQ50 ensures stable operation even during transient peak loads, allowing for a 99.5%+ efficiency rating while minimizing the risk of inductive heating.
What is the impact of multi-layer PCB interleaving in the PQ50 on Leakage Inductance (Lk) and switching losses in SiC-based high-frequency designs?
In high-speed SiC designs, parasitic parameters like Lk are the enemy of efficiency. The PQ50's planar structure allows for Interleaved Winding (placing secondary layers between primary layers). This tight magnetic coupling reduces Leakage Inductance to less than 0.1% of the total inductance. Lower Lk means significantly reduced voltage ringing and spikes across the SiC MOSFETs during switching, which allows for higher switching speeds with minimal EMI noise and eliminates the need for large, lossy snubber circuits.
Product Applications
Electric Vehicles (EV): The primary choice for high-power On-Board Chargers (OBC) and high-voltage DC-DC converters in commercial EVs and heavy-duty electric transport.
Renewable Energy Systems: Used in high-capacity Solar Inverters and bidirectional energy storage systems (ESS) for grid-scale power management.
Data Center Infrastructure: Powers high-wattage Server Power Shelves and UPS systems requiring extreme reliability and 80 PLUS Titanium efficiency levels.
Industrial High-Power Units: Ideal for plasma cutting machines, high-frequency induction heaters, and industrial laser power supplies.
Product Advantages
Extreme Power Density: Delivers up to 6000W+ in a footprint that is 40% smaller than traditional wire-wound PQ50 units, enabling ultra-compact power module designs.
Superior Thermal Dissipation: The flat, wide surface area of the PQ50 core facilitates rapid heat transfer. When mounted to a liquid-cooled cold plate or high-efficiency heatsink, it maintains an exceptionally low thermal resistance (Rth).
Unrivaled Parameter Consistency: Because the windings are etched or stamped via automated processes, every PQ50 unit produced has identical electrical parameters (Lk, Cp, resistance). This eliminates the performance variance often found in manual wire-winding.
Reduced AC Copper Losses: The flat conductor geometry effectively mitigates the Skin Effect and Proximity Effect at high frequencies, ensuring that the entire conductor cross-section carries current efficiently, unlike round-wire alternatives.
