High Current Toroidal Inductor with Flat Copper Wire and Fe-Si-Al Alloy Core for Photovoltaic Inverters (20kHz-100kHz)

This photovoltaic inverter toroidal inductor is wound with flat copper wire and serves as a core energy storage and filtering component in high-current applications. Specifically designed for photovoltaic inverters, its toroidal core structure efficiently concentrates the magnetic field, reducing magnetic leakage and energy loss.

• Low-Loss Fe-Si Core: Higher saturation currents compared to traditional ferrite cores, suitable for high-current applications with reduced high-frequency losses
• Flat Copper Wire Winding: Reduced skin effect for uniform current distribution at high frequencies and better heat dissipation with 20%–30% lower temperature rise than round wires

• Designed for sustained high currents (50A to 200A) in photovoltaic inverters
• Larger cross-sectional area of flat wires enhances current-carrying capacity while maintaining compact size
• Superior temperature performance compared to traditional round wire inductors

• Dual Ring Core Design: Stackable for flexible inductance value adjustment
• High Mechanical Strength: Tightly wound flat wires provide excellent vibration resistance for outdoor environments
• Automation-Friendly Production: Better consistency and easier machine-winding than round wires

• Filtering and energy storage in DC-AC conversion, suppressing high-frequency harmonics
• Critical component in MPPT (Maximum Power Point Tracking) circuits for enhanced power generation efficiency
• Low temperature rise design extends system lifespan by reducing aging of surrounding components
