COMSOL was used to simulate the variation of energy conversion efficiency with the permeability of electromagnetic shielding materials (ESM). It is found that the energy conversion efficiency is improved with the increase of μ' for lossless materials. However, there is the best match of μ' and μ" for the lossy materials. Based on the simulation results, the one-cycle energy consumption of the induction heated tobacco product (HTP) with different ESM was tested using a power analyzer. Among the range from 240 kHz to 320 kHz, the energy consumption is reduced with the increase of μ' for the ferrites. When μ' is 220, the one-cycle energy consumption can be reduced from 978.14 J to 833.40 J, and the energy conversion efficiency is increased by 14.08%. With the nano-crystalline materials, when μ=2064-j349, the one-cycle energy consumption can be reduced to 811.30 J, the energy conversion efficiency is increased by 17.06%. However, with the further increase of μ' and μ", the energy consumption is enlarged. The actual test results are basically consistent with the simulation. It is found that the energy conversion efficiency of HTP can be improved with proper ESM. [ABSTRACT FROM AUTHOR] |
