An inverter circuit which generates a output high frequency AC. A low frequency AC (LFAC) to high frequency AC (HFAC) power conversion system without a DC smoothing Capacitor filter is introduced. The operating principle of a utility frequency AC-high frequency AC power frequency conversion circuit defined as a high frequency inverter is described. This synthesized converter can be considered a...

thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. when high frequency is used for heating, it is called electromagnetic (em) heating. the applications of em heating for heavy-oil reservoi...

The paper deals with the traveling wave cylindrical heating systems. analysis presented is analytical and a multi-layer model using geometry used to obtain theoretical results. To validate results, practical constructed, tested results are compared ones. Comparison showed that adopted method efficient in describing performance of such induction
