Photovoltaic Inverter Ring Inductor Flat Copper Wire High-current Inductor Coil

1.Product Description

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. Combined with flat copper wire windings, it significantly lowers direct current resistance (DCR), enabling it to handle high current output and perfectly meet the high-power requirements during the conversion of direct current to alternating current in photovoltaic systems. Its high saturation flux density ensures stable inductance values even during current fluctuations, effectively suppressing harmonic interference and boosting inverter conversion efficiency to over 96%. Additionally, the compact ring design saves installation space, and high-temperature-resistant insulation materials ensure reliable operation in outdoor extreme environments ranging from -40°C to +150°C. This makes it a critical inductance component for stable power conversion support in photovoltaic power plants and distributed solar systems, ensuring efficient utilization of photovoltaic energy.

1. High Efficiency Power Conversion
Low-Loss Fe-Si Core

Compared to traditional ferrite cores, Fe-Si cores have higher saturation currents, making them suitable for high-current applications in photovoltaic inverters.

Low high-frequency losses reduce heat generation and improve system efficiency.

Flat Copper Wire Winding

Reduced skin effect: Current distribution is more uniform at high frequencies, reducing AC impedance.

Better heat dissipation performance: Flat wires have a larger surface area, resulting in a temperature rise that is 20%–30% lower than that of round wires.

2. High Current Handling Capacity
Photovoltaic inverters require sustained high currents (e.g., 50A to 200A), and traditional round wires are prone to overheating.

Flat wires have a larger cross-sectional area, enhancing current-carrying capacity while maintaining a compact size.

Actual measurement comparison: Temperature rise and current curves of flat wire inductors vs. round wire inductors under the same dimensions.

3. Structural Advantages
Dual Ring Core Design: Can be stacked for flexible adjustment of inductance values.

High Mechanical Strength: Flat wires are tightly wound, offering excellent vibration resistance, making them suitable for outdoor photovoltaic environments.

Automation-Friendly Production: Flat wires are easier to machine-wind, offering better consistency than round wires.

4. Key Role in PV Inverters
Filtering and energy storage in DC-AC conversion, suppressing high-frequency harmonics.

A critical component in MPPT (Maximum Power Point Tracking) circuits, enhancing power generation efficiency.

Extending system lifespan: Low temperature rise design reduces aging of surrounding components such as electrolytic capacitors.
