By a intelligent programming device CPLD, make IGBT induction heating power supply has the function of Fixed-angle&Phase locking/Frequency automatic tracking, etc. This design can improve the stability and efficiency. Because the machine has protect function of Over-frequency or Low-frequency unlock, it can accurately protect wire heating inductors from short circuit and open circuit fault4.Inverter circuit has function of Fixing angle/ Frequency tracking and control. When the operation condition is changing, the phase angle of inverter will not change, it has wide frequency suitable range5.Frequency sweep method: High accuracy of phase locking frequency, small attack. Start success ratio is 100%. Power regulating range: 10%-100%6.IGBT Induction heating device has wide application in heating treatment.Product CatalogueThe leading technology and quality----The complete production linesPC (Prestressed Concrete) steel bar production linesPC (Prestressed Concrete) steel wire production linesPC (Prestressed Concrete) Strand wire production lineSpring steel wire quenching and tempering production lineHigh Ductility Cold rolled ribbed steel bar production lineThe leading technology and quality----induction heating equipmentsMOSFET solid state high frequency welderIGBT solid state medium frequency/super audio frequency induction heating equipmentsSCR medium frequency induction heating equipmentsvacuum tube high frequency welder and induction heating equipmentsAll-digital control DC drive and large power DC power supply unitsCNC numerical control and PLC control standard & non-standard quenching machine tools, production line electric control complete equipmentslow voltage power network harmonic suppression and dynamic reactive power compensation devices.
