Compared with the prior art, the half-wave electromagnetic field generator has the advantages that the structure is simple, the cost is low, in addition, because of the arrangement of two IGBT tubes, the back pressure of the IGBT tubes is effectively controlled, the service life is long, and in addition, the efficiency of conveniently regulating the heating power is also realized.

Description

Technical field [0001] The present invention relates to the field of heating devices, and more specifically to a half-wave electromagnetic field generator, which is used to generate a high-frequency magnetic field so that a heating tube can generate heat based on the generated eddy current. Background technique [0002] At present, in the heating field, people have researched and developed an electromagnetic hot water pipe that can realize the separation of water and electricity, such as the Chinese utility model patent CN2713367Y, which forms a spiral pipe by tightly winding the coil on the outer ring of a section of insulated and non-magnetic water pipe. And a heating component is arranged in the spiral tube. In this way, when a high-frequency current is passed through the coil, a high-frequency alternating magnetic field is generated in the spiral tube, and the heating assembly generates eddy current heating under the action of the high-frequency alternating magnetic field, th...
