Internet Industry Induction Heating Development Trends

The implementation of "Made in China 2025" must conform to the development trend of "Internet +" and focus on the integration of informatization and industrialization. Liu Weisong, an expert in the field of induction heating equipment, said that only by accelerating the transformation from the factor-driven to the innovation-driven, turning the low-cost competitive advantage into a quality-effective competitive advantage, and changing the extensive manufacturing of resource-intensive, China's induction heating equipment industry may be able to The future world market has a place.

1) Large-capacity and high-frequency induction heating equipment Currently, inductively heating power-supply resonant inverters and soft-switching control are implemented. However, since inverters realize large-capacity and high-frequency power, they are used for power devices, cables, and There are many special requirements for wiring and grounding shielding. Therefore, some technical issues need to be further studied and solved.

Induction heating power is developing in the direction of intelligent control. “Internet+Industry” changes product attributes, and industrial integration into Internet technologies aims to turn dead products into live products, that is, to realize product data and intelligence. With the degree of automation of the induction heating processing line and the improvement of the reliability requirements of the power supply, the induction heating power supply is developing in the direction of intelligent control. The inductive heating power supply with the functions of computer intelligent interface, remote control, and automatic fault diagnosis is the next development goal of positive temperature measurement.

3) The equipment with high power factor and low harmonic pollution is called the important direction for future development. With the large consumption of resources and the emission of more pollutants, the transition from extensive manufacturing to green manufacturing will increase the demand for reactive power and harmonic pollution control of the entire power grid. Equipment with high power factor and low harmonic pollution will become an important direction for future development.

4) The best match between power supply and load will be the subject of research The induction heating power supply is mainly used in industrial sites, and the operating conditions are generally more complicated. Its liabilities are also varied. The output debt is combined with the power inverter to form an organic whole. The combination of load and inverter will directly affect the power factor of the power supply, that is, the power utilization. Therefore, the best match between power supply and load will also be one of the research topics.

In general, medium- and high-frequency induction heating power sources are moving toward higher power, higher frequency, smaller size, compactness, positive mounting, computerization, and online automation. It can be said with certainty that with the development of science and technology, induction heating technology and equipment will have more extensive applications. At the same time, it is necessary to combine the use of the “Internet” information technology to implement “Made in China 2025” and allow China’s induction heating equipment to “go out”.
