[0002] Three-phase AC reactors are commonly used reactive power compensation devices in power systems. Their main functions are to limit short-circuit current in the power grid, improve power quality, provide reactive power support, and protect electrical equipment. By introducing inductive reactance into the circuit, the reactor can effectively absorb harmonic energy, reduce voltage fluctuations, and improve system stability and efficiency.

[0003] The core-iron-silicon-aluminum-iron-yoke-silicon-steel hybrid magnetic circuit design is an innovative magnetic circuit structure that combines the properties of different materials to optimize the performance of the reactor.

Silicon iron and silicon aluminum materials generally have high magnetic permeability and low loss. These characteristics enable the hybrid magnetic circuit design to reduce the size and weight of the reactor while improving its energy efficiency and response speed.
