Product Description

The EE80 high frequency transformer is designed for high power isolated conversion in industrial inverters, UPS systems, battery chargers, renewable energy equipment, welding machines, and other power electronic platforms.

Its large ferrite core provides a substantial magnetic cross section and winding window for high current conductors, multiple secondary outputs, insulation barriers, shields, and protection devices. The winding can use parallel copper wires, litz wire, copper foil, or a combined conductor structure according to frequency, current, and loss requirements.

The pictured configuration incorporates multiple flexible lead wires and heavy duty crimp terminals for connection to power devices, busbars, or wiring assemblies. Lead length, wire gauge, insulation color, terminal type, and routing can be customized.

Chipsen can develop the EE80 transformer from a circuit specification, customer drawing, physical sample, or replacement requirement. The final design is confirmed through an approved drawing, electrical specification, and application validation.

Frequently Asked Questions

What information is required to customize an EE80 transformer?

Please provide the converter topology, input voltage range, output voltage and current, continuous and peak power, switching frequency, duty cycle, current waveform, target inductance, leakage limit, insulation requirement, maximum dimensions, cooling conditions, ambient temperature, and annual demand.

What power can an EE80 transformer handle?

Approximately 1 kW to 10 kW is a broad inquiry reference rather than a guaranteed rating. Actual power depends on topology, switching frequency, flux density, conductor design, cooling method, ambient temperature, efficiency target, and allowable temperature rise.

Can the EE80 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 current, frequency, skin effect, proximity loss, winding space, and termination requirements.

Can leakage inductance be customized?

Yes. Leakage inductance can be minimized for efficient power transfer or intentionally controlled for resonant and soft switching circuits. The required measurement frequency, test connection, and tolerance must be specified.

Can interwinding capacitance be reduced?

Yes. Winding arrangement, insulation spacing, sectional winding, and electrostatic shielding can be evaluated. Reducing capacitance may affect leakage inductance, winding space, and thermal performance.

Can multiple secondary outputs be provided?

Yes. Multiple isolated or connected secondary windings can be developed when power distribution, winding space, insulation, and temperature requirements permit.

Can this transformer be used in an LLC converter?

Yes. An EE80 transformer can be developed for LLC resonant conversion. The resonant operating range, magnetizing inductance, leakage inductance, turns ratio, gain requirement, and load range must be provided.

Can the transformer support high voltage isolation?

Yes. Reinforced insulation barriers, suitable materials, creepage, clearance, and high voltage testing can be incorporated according to the applicable standard and working voltage.

Can a temperature sensor be installed?

Yes. Thermistors, thermostats, thermal fuses, and other temperature sensing or protection devices can be evaluated according to the control system.

Can the lead wires and terminals be customized?

Yes. Wire gauge, insulation type, color, length, routing, identification, and terminal style can be customized according to the approved drawing.

Can Chipsen develop a replacement from an existing sample?

Yes. Chipsen supports sample based replacement development. The sample can be evaluated for dimensions, turns ratio, inductance, resistance, winding arrangement, leads, and terminals. Actual converter conditions are still required for correct magnetic and thermal design.

Is the EE80 suitable for continuous operation?

A continuous duty version can be developed after confirming the RMS currents, frequency, waveform, ambient temperature, cooling method, enclosure conditions, and allowable temperature rise.

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.
