IGBT inverter
IGBT converters and generators with state-of-the-art IGBT(insulated-gate bipolartransistor) or MOSFET(metal-oxide-semiconductor field-effect transistor) technology combine durability and robustness with high energy efficiency.
Structure and mode of operation
In addition to the coil, the generator or converter is the most important element in an induction heating system. The input voltage is commutated from the mains frequency to a frequency required by the process. The basic structure of a converter consists of the rectifier and the inverter. The rectifier consists of power diodes and converts the mains-side AC voltage into a DC voltage signal. In modern inverters, the downstream inverter consists of transistors that generate the desired frequency through controlled switching operations. The introduction of transistor technology has significantly reduced switching losses and increased efficiency to up to 98%. Depending on the power range, MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) or IGBTs (Insulated Gate Bipolar Transistor) are used. As a rule, MOSFETs are used in the low power range up to approx. 20 kW, while IGBT converters are used to achieve outputs of several megawatts.
Areas of application for modern IGBT inverters
The areas of application for modern generators and IGBT converters are very diverse. The following list only provides a rough overview of the possible applications:
- Heating tapes, wires
- Hardening, tempering and quenching
- Soldering and welding
- Melting of iron and non-ferrous metals
- Forging and forming of ingots, billets, bars, tubes and tube ends
