  • Drive control method for an electromagnetic induction heating apparatus
    Patent number: 5026955
    Abstract: A method for controlling the drive of an electromagnetic induction heating apparatus jointly utilizing a time control method and a linear control method. The method includes the steps of storing pulse signals and reset pulse signals in addresses of a memory of a micro-processor, short-circuiting an ON/OFF switch by storing pulse signals of different widths in addresses of the memory, controlling a power transistor by a time control method when the power level is below a predetermined level, and controlling the power transistor by a linear control method when the power level is above a predetermined level. Thereby, a flicker effect and noise as prevented from being generated.
