Current Hot Complete Induction Heating Equipment (XZ-600B): 1. Based on the PLL inverter frequency tracking technology, realize inverter frequency can accurately track the instantaneous load changes. To adjust the inverter frequency and phase timely. Ensure IGBT works consistently in ZCS state, realize the IGBT "soft switch" function. Avoid IGBT working at high peak voltage, and reduce the loss of the IGBT and system effectively. Reduce the IGBT fever, to solve the problem of easily IGBT damage. 2. Perfect restrictions, protection functions. Have the features of over voltage, over current, over hot, lack water, lack phase, over frequency etc alarming protective circuit. To prevent accidental situation damage to equipment. Ensure the equipment reliability and stability. 3. Adopt with independent intellectual property rights of the ZPT technology, equipment net side has high power factor, without any pollution to the grid. 4. Based on PID power control technology, the output power is stable at ± 1%. Output power is at 10-100% can adjust continuously.
