It can be understood that the working state of the induction cooker can be preset during product development, and can also be adaptively adjusted according to the use requirement in practical application, in one embodiment, according to the heating mode of the induction cooker (the heating mode includes continuous heating and intermittent heating), when the induction cooker is in the second working state, the induction cooker is continuously heated, and when the induction cooker is in the first working state, a pulse driving signal after chopping is output to the IGBT device so as to control the induction cooker to be in the intermittent heating state.

As shown in the embodiment of fig. 8, when the induction cooker is continuously heated in the second working state, pulse control signals with the same width are continuously output, so that the collector voltage of the IGBT device is kept continuous, and by adjusting the width of the pulse control signals, the collector voltage of the IGBT device can be increased or decreased, thereby realizing the effect of adjusting the actual output power of the induction cooker.
As shown in the embodiment of fig. 8, when the induction cooker is intermittently heated in the first working state, the pulse control signal is set to chop from the starting time of the chopping period, after the chopping time of the chopping period is obtained by calculation, a chopping area is determined according to the chopping time and the chopping starting time, and in the chopping area, the pulse control signal is suspended to be output, the voltage value of the collector voltage of the IGBT device in the chopping area is 0, so that the effect of intermittently driving the induction cooker to heat is achieved, and by adjusting the width of the chopping area, the time length for which the voltage value of the collector voltage of the IGBT device is 0 can be prolonged or reduced, so that the effect of adjusting the actual output power of the induction cooker is achieved.

Referring to fig. 4, in one embodiment, the step of adjusting the width or chopping duration of the pulse driving signal according to the comparison result of the actual output power of the induction cooker and the target power may include, but is not limited to, steps S401 to S403.
Step S401, calculating the chopping time length of each chopping period according to the ratio of the actual output power to the minimum continuous power, or calculating the chopping time length of each chopping period according to the ratio of the actual output power to the characteristic on power. The characteristic turn-on power is the power corresponding to the preset characteristic turn-on voltage.
In step S401 of an embodiment, a ratio of the actual output power to the minimum continuous power is calculated to obtain a first ratio, and a chopping duration and a chopping start time corresponding to the first ratio are calculated according to a preset chopping logic, where the ratio of the chopping duration to the duration of the chopping period and the ratio of the actual output power to the minimum continuous power are positively correlated.

Step S402, setting chopping areas of pulse control signals in each chopping period according to chopping time lengths.
Specifically, in step S402, the chopping duration and the chopping start time corresponding to the first ratio are set according to the preset chopping logic, the chopping area is determined according to the chopping duration and the chopping start time, the period of time from the start time of the chopping start time over one chopping duration is the chopping area of the chopping cycle, for example, the chopping start time may be the start time of each chopping cycle, and when one chopping cycle starts, the period of time from the start time of the chopping cycle over one chopping duration is the chopping area of the chopping cycle.
Step S403, performing chopping processing on the output pulse control signal according to the chopping region.
Specifically, in step S403, the pulse control signal is chopped in the set chopping area, and the pulse control signal is chopped once in each chopping period, so that the break time of the pulse driving signal is periodically adjusted, the chopped pulse driving signal is output, and the induction cooker is controlled to perform intermittent heating, so that the heating continuity of the induction cooker can be improved and the noise can be reduced.
According to the induction cooker heating method provided by the embodiment of the application, the switching between the first working state and the second working state can be realized according to one of the following three modes.

The characteristic turn-on voltage is the maximum turn-on voltage value of the IGBT device, that is, the characteristic turn-on voltage is the maximum value of the voltage to ground immediately before the collector of the IGBT device turns on.
When the electromagnetic oven is in the second working state, controlling the electromagnetic oven to continuously heat, when the characteristic opening voltage is smaller than or close to a preset voltage threshold value and the actual output power is larger than the target power, carrying out chopping treatment on the pulse driving signal, regulating the break time of the pulse driving signal according to the chopping area by periodically setting the chopping area, and outputting the regulated pulse driving signal to control the electromagnetic oven to heat so as to enable the electromagnetic oven to be converted into the first working state to intermittently heat.
When the induction cooker is in a first working state, the induction cooker is controlled to intermittently heat, the width of a pulse driving signal is regulated so that the characteristic opening voltage is not larger than the threshold voltage, when the width of the pulse driving signal is increased, the characteristic opening voltage is reduced, when the width of the pulse driving signal is reduced, the characteristic opening voltage is increased, the actual output power is regulated by regulating the chopping time length, when the actual output power of the induction cooker is larger than the target power, the chopping time length of the pulse driving signal is increased, when the actual output power of the induction cooker is smaller than the target power, the chopping time length of the pulse driving signal is reduced, and when the chopping time length is zero and the actual output power is still smaller than the target power, the induction cooker is switched to a second working state.
