Before the age of 50, induction heating device key are: power frequency induction melting furnace
, electromagnetic frequency multiplier, intermediate frequency generator and tube oscillators type high voltage power supply.
The emergence of 50 times at the end of the SCR means solid modern integrated circuit technology as the key power electronics at first.
The emergence of the silicon thyristor promoted the induction heat power and by using the rapid development of medium frequency induction heating equipment
Foshan medium frequency induction heating equipment so far, in the high frequency (
500 hz ~ 10 khz)
Scope, thyristor medium frequency induction heating equipment has replaced the traditional medium frequency generator and the electromagnetic induction frequency multiplier.
In the range of high frequency, because of the thyristor power switch itself characteristics of main parameters such as limit, to research the frequency switching power supply produced high technical level, it must according to change the power circuit topology is will remain.
Guangdong medium frequency induction heating equipment at the beginning of 70 to 80 at the end of the age, the contemporary single-chip integrated semiconductor materials production and processing technology and the fusion of the output power of semiconductor technology, for the development and design new presented the standard output power integrated circuit technology, have a large number of all control type power electronic technology integrated circuit technology, greatly promoted the development trend of power electronics, for solid super audio, high-frequency power supply, medium frequency induction heating equipment research and development to produce a solid foundation.
Heng Yang medium frequency induction heating equipment IGBT introduced into - 1983
Step to promote the development trend of induction heating equipment, comprehensive the MOS and the advantages of bipolar transistor IGBT, state voltage decreases, the power switch is faster, the advantages of the easy to drive, since 1988, when processing the qing after living dilemma, IGBT power high speed has become many components of medium frequency induction heating equipment, frequency of 100 KHZ power output reached MW grade switching power supply can be maintained.
