Key Points For Purchasing High-Frequency Induction Heating Power Supplies

1. Select power semiconductor devices with high operating frequencies. Since they need to be applicable to different scenarios and meet customer requirements, consideration can be given to choosing MOSFETs, SITs, or IGBTs-all three modules have distinct advantages.

2. Adopt soft-switching technology to increase the operating frequency. The switching devices of high-frequency induction heating power supplies incur significant losses, which not only reduce power supply efficiency but also cause high temperature rises, requiring a well-designed heat dissipation system. To minimize switching losses, the selection of soft-switching conversion technology is a better choice; it is also a key technology for realizing the high-efficiency development and application of high-frequency induction heating power supplies.

3. Frequency-doubling inverter bridges are of great significance for improving the heating frequency and power of power supplies. This structure can better exert the performance of IGBT power devices: with 8 independent power switching devices that can operate in four phases, the frequency of the AC voltage and current obtained by the common load is doubled.

In the industry and market of induction heating power supplies, whether a technology-oriented enterprise can provide high-frequency induction heating power supplies with higher performance basically reflects its technical strength. Therefore, when purchasing high-frequency induction heating power supplies, it is essential to pay attention to the three points mentioned above. Keeping these three points in mind can prevent unexpected issues and better ensure the quality of the purchased power supply. We welcome everyone to leave comments for communication and exchange.
