Description
Compact Efficient PQ50 High Frequency Transformer Low Loss Stable for UPS
The PQ50 is a high frequency ferrite transformer platform developed for compact isolated power conversion. Its PQ core geometry provides a relatively large magnetic cross section and winding area within a compact installation envelope, making it suitable for applications requiring power density, efficiency, controlled leakage inductance, and stable thermal performance.
The image shows two magnetic assemblies installed on a shared base. This may represent a customer-specific transformer assembly rather than one standard PQ50 configuration. The quantity of magnetic components, wiring arrangement, mounting base, and electrical relationship must be confirmed through the approved drawing.
All numerical values below are typical engineering inquiry references rather than guaranteed ratings. Final performance depends on converter topology, input voltage, output requirements, switching frequency, duty cycle, waveform, cooling method, insulation system, and allowable temperature rise.

What power can a PQ50 transformer handle?
Approximately 300 W to 3 kW is a broad inquiry reference rather than a guaranteed rating. Actual capacity depends on topology, switching frequency, flux density, winding design, cooling, ambient temperature, efficiency target, and allowable temperature rise.
What is the advantage of a PQ core?
A PQ core provides a relatively large magnetic cross section and winding window within a compact geometry. This can support high power density, efficient winding arrangements, and reduced overall converter size.
Can the PQ50 be used in an LLC converter?
Yes. A PQ50 transformer can be developed for LLC resonant conversion. The resonant frequency range, turns ratio, magnetizing inductance, leakage inductance, gain requirement, and load range must be provided.
Can leakage inductance be customized?
Yes. Leakage inductance can be minimized for efficient coupling or intentionally controlled for resonant operation. The required value, tolerance, frequency, and test connection must be specified.
Can the transformer use litz wire or copper foil?
Yes. Round wire, parallel wire, litz wire, copper foil, and combined winding structures can be evaluated according to frequency, current, loss, winding space, and termination requirements.
Can multiple secondary outputs be provided?
Yes. Multiple isolated or connected secondary windings can be developed when winding space, power distribution, insulation, and thermal requirements permit.
Can Chipsen produce the two transformer assembly shown in the image?
Yes. A customized assembly using multiple magnetic components on a shared mounting base can be evaluated. The electrical relationship, wiring diagram, dimensions, mounting points, and mechanical requirements must be provided.
Can interwinding capacitance be reduced?
Yes. Winding sequence, insulation spacing, sectional construction, and electrostatic shielding can be optimized. Reducing capacitance may affect leakage inductance, dimensions, and thermal performance.
Can the PCB pin arrangement be customized?
Yes. Pin quantity, spacing, diameter, position, polarity, and electrical assignment can be developed according to the customer PCB drawing.
Can high voltage isolation be provided?
Yes. Reinforced insulation, suitable barriers, creepage, clearance, and dielectric testing can be incorporated according to working voltage and the applicable safety standard.
Can Chipsen develop a replacement from a physical sample?
Yes. The sample can be evaluated for dimensions, turns ratio, inductance, DCR, winding arrangement, pinout, and assembly. Actual converter operating conditions are still required.
Can samples be produced within seven days?
Seven day sample production is a target for eligible designs after the drawing, electrical requirements, materials, and test conditions are confirmed. Special tooling or materials may require additional time.
Are the specifications on this page guaranteed?
No. They are typical engineering and purchasing references. Only values confirmed in the approved drawing, product specification, and validation documentation are guaranteed for the final product.
