Definitions

  • the electromagnetic resonance circuit of a single IGBT generally adopts a parallel resonance mode, and sets a resonance parameter under the premise of realizing high-power operation, as shown in FIG. 1 , when heating with high power, due to the relationship of resonance parameter matching, Therefore, the lead voltage at the time when the IGBT is turned on is very small, and the pulse current of the IGBT is also very small.
  • the problem is that if continuous low-power heating is used, as shown in Fig. 2, the lead voltage of the IGBT is very high, resulting in a very large pulse current of the IGBT, and it is particularly easy to exceed the use limit of the IGBT and damage the IGBT.
  • the intermittent heating method may affect the cooking function, such as easy spillage during porridge, reducing the user's cooking experience.
  • a first object of the present invention is to provide a control method of an electromagnetic heating system capable of achieving continuous low-power heating while effectively suppressing the pulse current of the power switch tube.
  • control method of the electromagnetic heating system according to the above embodiment of the present invention may further have the following additional technical features:
  • control unit is further configured to: when the target heating power is greater than or equal to the preset power, control the driving unit to continuously provide the second driving voltage in each turn-on control period To the power switch tube.
  • a third aspect of the present invention proposes an electromagnetic heating system including the control device of the electromagnetic heating system in the above embodiment.
  • FIG. 1 is a schematic diagram showing driving waveforms of an IGBT when an electromagnetic heating system is heated at a high power in the related art

Abstract

La présente invention concerne un procédé de commande d'un système de chauffage électromagnétique, comprenant les étapes suivantes consistant à : acquérir une puissance de chauffage cible du système de chauffage électromagnétique ; déterminer si la puissance de chauffage cible est inférieure à une puissance prédéfinie ; si la puissance de chauffage cible est inférieure à la puissance prédéfinie, dans chaque période de commande de mise sous tension, fournir d'abord une première tension d'attaque à un transistor de commutation de puissance dans le système de chauffage électromagnétique, et une seconde tension d'attaque au transistor de commutation de puissance après un temps prédéfini, la première tension d'attaque étant inférieure à la seconde tension d'attaque. Ainsi, un chauffage continu à faible puissance peut être réalisé, et le courant d'impulsion du transistor de commutation de puissance peut être efficacement supprimé. La présente invention concerne en outre un dispositif de commande du système de chauffage électromagnétique et un système de chauffage électromagnétique.
