摘要
Abstract
At present,the induction heating power supply technology is mainly towards?the direction of high power,high frequency and intelligent control technology.However,with the increase of the inverter switching frequency,the switching loss of power devices is increasing as well.With the outstanding advantages of high critical avalanche breakdown electric field strength,high thermal conductivity,low dielectric constant,the application of SiC MOSFET,as a wide band gap semiconductor materials,provides an ideal solution for this problem.In this paper,the design of induction heating power supply inverter,and the corresponding drive circuits for SiC MOSFET and the power scaling are studied in detail.Finally,a new type of induction heating power supply with frequency of more than 800 kHz and single inverter bridge power over 50 kW has been developed.By the parallel connection of the inverter bridge,the power supply of the single machine capacity is up to 200 kW,which fills up the blank in the field of induction heating by the new SiC MOSFET device to a certain extent.关键词
