Abstract

In order to solve the electromagnetic heaters´ problems of high switching losses and resonant frequency drifting in harsh industrial environments, in this paper, we introduce the soft-switching technology to make the IGBT work on the condition of zero-current turning on and zero-voltage turning off to reduce switching losses, and the IGBT drivers auto adjust the driving frequency to achieve frequency synchronization and adapt the drifting of resonant frequency, in this way, the electromagnetic heaters´ adaptability and thermal efficiency can be improved.
