This paper presents an innovative curved-air-gapped (CAG) inductor solution, it can be beneficial to improve harmonic issue related with lighting equipment applications. The effective mathematical inductance model of proposed CAG design is derived and verified experimentally in terms of harmonic and EMI emissions. A new LC filter configuration is examined to improve 2nd and 3rd order harmonic effectively. A complete optimal PFC inductor design procedure is given in terms of power loss and three different ferrite materials.
