Experimental Verification of 2.4 kVAr and 12 kVAr Prototype Variable Inductors Controlled By Virtual Air Gaps With Magnetic Orthogonality

A Review of Tunable Inductors for Power Electronics: Techniques and Applications

“…Additionally, its usage can be extended to reactive power compensation, harmonic filtering, and other power systemrelated applications. Different configurations for the realization of this technique have been proposed in previous literature, such as in [56][57][58][59][60][61][62][63][64][65][66][67].…”

“…During the manufacturing process of the two cores, an unintentionally fixed actual air gap might be created, which should be minimized if not completely eliminated. The insertion of a small air gap can increase the inductance's tunability range and extend the inductor's power range [59]. On the other hand, a larger air gap can have a negative impact on the inductance tunability range, resulting in a reduced range [58].…”
