Features and applications of IGBT induction heating power supply in induction heating furnace

Time: 2019-09-09 Reading: 71

Chengdu Duolin Electromechanical Equipment Co., Ltd. is a professional manufacturer of medium frequency induction heating furnace. IGBT induction heating power supply is an important supporting equipment in the induction heating furnace. Whether the equipment can run smoothly, can save energy, can be produced in environmental protection, and whether the heating is uniform, etc. are closely related to it.


Duolin has advanced mechanical and electrical skills, complete product varieties, stability, reliability, safety and efficiency. Over the years, we have formed accurate and prudent production processes and established a comprehensive after-sales service system. Ensure that each set of intermediate frequency induction heating furnace we produce can play an advantage at the user's application site.


IGBT induction heating power has been developed in China for decades, and its use is widespread. Today, we will introduce you the features and use of IGBT intermediate frequency induction heating power in induction heating furnace.

Inductive power sources used in the heat treatment of metal workpieces include thyristor induction power sources and IGBT power sources. However, the advantages of IGBT induction heating power sources have gradually become apparent through long-term use, so more and more users choose IGBT induction power supply.


Compared with thyristor intermediate frequency induction heating power, IGBT intermediate frequency induction heating power has the following characteristics

1. IGBT induction heating power supply has high power, high inverter output voltage, small current, and low line consumption. It is an energy-saving power supply. The power factor is about 10% higher than the thyristor intermediate frequency power supply, and can generally reach more than 95%.

2. The output power stabilizes the IGBT inverter frequency to follow the load change. When the resistivity and magnetic permeability of the heated metal temperature are added, the operating frequency of the power supply is also randomly changed, and the active frequency is tracked when it reaches the full resonance frequency, and the power frequency is adjusted to complete the power supply. Active conditioning output power, that is, variable frequency power conditioning. As a result, the output power is stable, and the heating power is significantly improved.

3. Harmonic disturbance to the power grid The small harmonics generated by the small IGBT intermediate frequency inverter power supply are small, and the harmonic disturbance to the power grid is weak.


With the development of modernization, intelligence, high efficiency, energy saving, and environmental protection have gradually become important directions for development among enterprises. Doolin Electromechanical Induction Heat Treatment Furnace is equipped with IGBT induction heating power supply, which allows the equipment to actively track the completion frequency of production, and various closed-loop controls are freely adjustable. Users have a variety of different personalized production needs.
