Conventional converter transformer at high frequencies, which have localized hot spots in central core. Therefore, in order to reduce the thermal effects, when conventional converter transformer operating frequency increases, it must accordingly reduce its flux density sensing equipment products in the product, increasing its volume. This makes it impossible to use it to do high power density power. Ideal for low output voltage converter, its step-down ratio is high. When a conventional converter transformer, generally a turn output winding, approximately 32 turn primary winding. Thus, the primary winding arrangement would need a multi-layer, thus winding between the leakage inductance and high capacitance, serious adverse factors such as skin and proximity effects are present in the converter transformer. With the induced current local heating of the workpiece surface heat treatment process. This surface hardening heat treatment process used in induction heating equipment in the product can also be used for local annealing or tempering product sensing devices, sometimes for the overall quenching and tempering. The early 1930s, the United States, the Soviet Union began to use induction heating method has the parts for surface hardening. With direct sensing devices in the product development industry, induction heating heat treatment technology continues to improve, the application scope has been expanded. And high frequency induction heating technology is currently the most efficient metal material is heated, the fastest, and low consumption and environmental protection. It has been widely used in various industries for thermal processing of metallic materials, heat treatment, hot assembly and welding, smelting process. It can not only overall heating of the workpiece, but also targeted local heating of the workpiece; workpiece can be achieved through the deep heat, but also its surface only, centralized heating surface; not only direct heating of the metal material, but also on non-metallic Materials for indirect heating. And so on. Therefore, induction heating technology will more and more widely applied in all walks of life.
