As solid-state Medium-frequency frequency converter power supply Thanks to the rapid advancement of control technologies and the availability of high-quality, low-cost electronic switching devices, the electrical efficiency of these systems has steadily improved, currently reaching 96% to 97%. As metal heat preservation and melting equipment, enterprises seeking medium-frequency induction furnaces prioritize high reliability, high efficiency, and low cost. Today, in the manufacturing and maintenance of medium-frequency inverters, domestically produced high-quality thyristors are used as electronic switching devices; reactors are made using high-quality silicon steel sheets also sourced domestically, with large-diameter disc-type windings optimized for superior performance. Filtering and compensation capacitors are composed of high-quality domestic electrothermal capacitors, and all connecting components—including copper busbars and water-cooled cables—are crafted from premium, fully-gauge copper plates and cables. The induction coils and furnace bodies are constructed using No. 1 special-shaped square tubes made of oxygen-free copper. Extensive operational experience has demonstrated that this combination of hardware components provides a solid foundation for medium-frequency induction furnaces to operate with high reliability, high efficiency, and low costs. In particular, for medium- and large-sized medium-frequency furnaces—those with capacities exceeding one ton—the advantages of selecting high-quality, domestically produced components and materials become even more pronounced: the larger the furnace, the more evident the benefits of enhanced reliability, efficiency, and cost-effectiveness.
