Balanced Three-Phase Inductance:Symmetrical magnetic circuit ensures excellent phase balance and current sharing.
Precision & Compactness:Closed-core design guarantees accurate inductance, high saturation resistance, and a minimized footprint.
Inrush Current Suppression:Limits peak currents during capacitor bank or rectifier bridge energization.
Harmonic Attenuation: Provides high series impedance to 5th, 7th, and 11th order harmonics, reducing grid-side THD (standard impedance: 2%~4%).
Voltage Spike Mitigation:Buffers against voltage transients from upstream switching operations and lightning surges.
DC Bus Ripple Reduction:Smooths input current, thereby reducing ripple current on the DC bus and stress on the inverter stage.
Robust Mechanical Structure:Uniform column height and symmetrical layout counteract radial and axial short-circuit forces, offering superior deformation resistance compared to stacked single-column designs.
Efficient Thermal Performance: Optimized inter-column airflow and uniform heat dissipation surface ensure stable temperature rise in dry-type epoxy cast designs.
Cost-Effective Manufacturing: Standardized winding molds for all three phases streamline production and reduce tooling costs.
