(54) | POWER CONTROL METHOD AND INDUCTION COOKER |
(57) The embodiments of the present disclosure provide a power control method and an induction
cooker. The power control method include : obtaining a working mode of an induction
cooker; when the induction cooker is in a working mode with a single heating zone
working, obtaining a first Insulated Gate Bipolar Transistor (IGBT) temperature of
the working heating zone, and based on the first IGBT temperature, obtaining a first
maximum power value of the working heating zone; when the induction cooker is in a
working mode with multiple heating zones working, obtaining a second IGBT temperature
and a working time of the working heating zones, and based on the second IGBT temperature
and the working time, obtaining a second maximum power value of the working heating
zones. According to different working modes, different power control solutions can
be prepared and by a proper temperature hysteresis error, an excessively high IGBT
temperature can be avoided and thus the induction cooker is prevented from entering
a high-temperature protection mode mistakenly.
