Samsung patents induction cooker tech to balance heat across multiple burners
Samsung has filed a patent for an induction heating system that uses multiple power converters to heat different cooking zones. The device monitors the power output of each zone and automatically adjusts the electrical signal to ensure the heat is distributed evenly across all burners.
In the filing’s own words
An induction heating device to control power distribution, and a control method therefor. The induction heating device includes a configuration in which power that is output from a plurality of inverters included in the induction heating device is detected and, based on the ratio between the detected powers exceeding or being less than a set ratio, the duty of a switching element included in at least one from among the plurality of inverters is adjusted to uniformly distribute power that is output from the plurality of inverters.
What exactly they claim (claim 1)
1. An induction heating device including a plurality of working coils, the induction heating device comprising: a first inverter configured to supply current to a first working coil among the plurality of working coils; a second inverter configured to supply current to a second working coil among the plurality of working coils; a memory to store at least one instruction; and at least one processor configured to execute the at least one instruction to control operations of the first inverter and the second inverter, wherein the at least one processor is configured to: obtain a first power output from the first inverter, obtain a second power output from the second inverter, obtain a ratio value between the first power and the second power, and based on the obtained ratio value being greater than or less than a set ratio value, adjust a duty of a switching device provided in at least one of the first inverter and the second inverter such that the ratio value is included in the set ratio value.
