Crystal growth power supply is a medium frequency induction heating power supply designed specifically for single crystal growth furnaces using vapor deposition method. The power supply adopts an AC-DC-AC frequency conversion method with high efficiency and stability. The electromagnetic induction generated by the coil directly acts on the heated material, causing it to induce high-density eddy currents and generate heat; For metal heating, compared to other heating methods, it has the advantages of high thermal efficiency, less heat loss, rapid heating, energy saving, less environmental pollution, easy control and adjustment, capable of handling high-performance and high demand situations, convenient maintenance, easy installation for production, low investment, short cycle, fast effectiveness, and simple process in the crystal growing machine.These benefits have made it a popular choice among induction heating manufacturers.
