Inducing heating has become an essential part of our life, and it also plays an important role in actual life. GuangYuan · GuangZhiYuan Technology Production is also in accordance with people 's needs.
(1) Unity of high power and high frequency
The use frequency and large capacity of the power semiconductor device are mutually restriction, resulting in a long period of time to obtain high-power and high frequencies. However, with the rapid development of the power electronic device, such as IGBT, MOSFET, etc., future induction heating technologies must develop in the direction of high frequency and high frequency.
(2) Realization of low loss and high power factor
The new power switching device is small, causing a small pressure drop, so that the loss of the system is mainly manifested on the switch loss of the device in high frequency. How to reduce the switching loss of the device, improve the power factor becomes a future development direction. However, the introduction of resonant technology and the application of phase-locked loop technologies have greatly reduced the opening and turnover loss of switching devices in the power supply, and lock the operating frequency of the power supply in the resonant range, making the power factor increase possible.
(3) Ninghua and intelligence of sensing heating power control circuit
When the sensing heating power supply is controlled by analog circuit, there are some inevitable disadvantages, such as components, age, debugging difficulties. In recent years, the induction heating treatment line is getting closer to automation control, and the requirements for power supply reliability are also improved, corresponding to this, induction heating power supply is also developing in the direction of digitalization, intelligent control.
