Main features and performance comparison of WTR frequency conversion induction heater
1) All-air cooling structure
The IGBT inverter and output isolation transformer of the system adopt air cooling structure, so the water system fault is completely eliminated, the problem of the output transformer is easily damaged, the reliability is significantly improved, and the loss is lower.
2) The DSP main processor
WTR induction heater takes the lead in using DSP central processor, which has extremely high processing speed, ensures the efficient and orderly operation of various functions of the device, has real-time computing ability and real-time simulation and simulation ability, and the device reliability is extremely high. Compared with the conventional processor, the accuracy of the control and measurement is significantly improved. The limitations, speed and reliability of protection increase, and the function of quantity processing and display operations increase greatly.
3) Three heating modes
The heating system has three control modes: timing control, temperature control and insulation control, which can be flexibly selected according to user requirements.
4) Fast IGBT drive
The system adopts German Infineon IGBT frequency conversion half bridge structure, compared with the current drive circuit, can significantly improve the resonance waveform, reduce the dead time, and further reduce the switching loss, improve the thermal efficiency, increase the stability of high frequency tracking inverter; and has short circuit protection and undervoltage protection function.
5) Automatic and accurate tracking of the resonant frequency
Based on the fast and accurate processing of the DSP processor, the accuracy and speed of the tracking frequency are significantly improved, ensuring that the system always works near the optimal working point.
