Through the literature material[13],when lines are excitated with frequency 40kHz and 18kV voltage,melting ice is in the most obvious effect.Therefore,the parameters of ice melting device model diagram of transformer and PWM generator can be adjusted.The transmission line alternating current is as excitation source,through AC-DC-AC frequency conversion after the transformation of the transformer,the best ice melting power with voltage of 18 kV and frequency of 40 kHz is obtained.Taking into account the inverter to the rated voltage and the economy of ice melting device, the device sequence takes voltage transformation firstly,then frequency conversion.

Khalili et al. [5] published a research whose objective is the study of the drying process of ceramic materials with known chemical composition and to analyze the process using the method of analysis of the Finite Elements.
The most recent literature comes, therefore, demonstrating the power of numerical simulation in reproducing the drying processes of materials.
Drying has been applied to different materials, such as: grains, fruits, vegetables, wood, ceramic products, etc.
In addition, controlling the migration of water inside the materials allows preventing the surface layer dry faster than the rest of the material, avoiding structural damage.
