The design of small power induction heating power supply
Abstract：With the development of technology, induction heating technology as a new type of clean, efficient heat energy, more and more used in the production and living among the people. Induction heating with heating speed, high thermal efficiency, suitable for local heating, product quality, no pollution, easy-to-production automation, etc., the power density in the work piece is heated and its distribution can be easily by frequency selection and induction loop be. At present, the induction heating technology has been widely used in metal melting, casting, welding, heat treatment, hot forging and other hot working processes. for small work piece surface heat or ultra-small small parts machining and welding, require more concentrated power, the output frequency is more High, but the frequency increases switching speed by the device itself and the technical process of the limit.
This paper analyzes the principle of induction heating power supply, and understand the status of the induction heating power supply. Through the two parts to design of induction heating power supply. The first part is the design of coil to induction heating power supply and water cooling unit through theory.The second part is choose full-bridge IGBT module as an inverter circuit. Build a IGBT drive circuit as the frequency. Finally, summarizes the design.
KeyWords：Induction heating ；Water cooling unit ；Inverse circuit
