感应加热电源设计得出结论A Design Of Induction Heating Power Inverter Abstract Induction heating can be used for metal smelting, diathermy, heat reatment and welding process, the manufacturing sector has become an indispensable technology in metallurgy, defense, machining and other departments and ships, airplanes, cars and so on. Besides induction heating is constantly entering peoples family life, such as induction cooker, etc. are relying on the principle of induction heating work. Induction heating power supply is the development trend of high-frequency, high-capacity, intelligent and green. The current high-frequency induction heating power of about a few hundred kilohertz frequency technology is relatively mature. In this paper, the series half-bridge induction heating power supply for the study, first principles on the basis of introduction of induction heating, induction heating power supply elaborated characteristics, domestic development and should its development trend. Secondly, it introduces the advantages and disadvantages of full-bridge inverter circuit in series with a series of half-bridge inverter circuit, half-bridge resonant inverter series has a simple structure, easy to control, good economic returns, etc. Therefore, the inverse analysis of the half-bridge series variable working principle of the bridge. Again, on the basis of a series of half-bridge inverter circuit designed on the specific circuit parameters were calculated for each device, and a reasonable choice of components. Finally, in a half-bridge series resonant power supply voltage by changing the rectifier filter after testing the leg voltage waveform, and the waveform is a brief analysis, the induction heating power should avoid no-load and other experimental results.
