The purpose of this Major Qualifying Project was to understand the relationship between core airgap length and inductance. This knowledge was used to create a tunable inductor that operates similarly to a potentiometer. This inductor could be integrated into real world applications, such as filters and DC-DC power converters. It allows the capability to adjust inductance values without replacing the inductor. The team modeled and built a five-layer tunable planar inductor to test this concept. The process started with research into planar inductors and their applications. The team then modeled and simulated 3-D single and multi-layer inductors using Ansys Maxwell. Finally, the team designed and fabricated multiple printed circuit board (PCB) planar inductors and tested them through multiple procedures in a lab setting.
