Electrical Control:Electrical appliance introduction

IGBT Induction heating power supply feature

1. Main elements are Germany SIEMENS 400A/1200V big power IGBT consist parallel circle, have a good capability of frequency automatic tracking

2. Voltage/Current double closed circuit control, this mode has constant voltage operation feature, it means the voltage of inductors will not be influenced by Inlet voltage/Load resistor, etc. Constant voltage make the load heating most stable

3. Adopt the most advanced control technology in the world. 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 fault

4. 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 range

5. 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.
