An induction heating-type cooktop comprising:
- a working coil configured to heat a cooking vessel;
- an inverter configured to supply current to the working coil, the inverter including a plurality of switching elements;
- and
- a controller configured to:
- in response to the cooking vessel being a magnetic type of cooking vessel, set an operating frequency of the inverter to a value that is greater than a first resonate frequency;
- and
- in response to the cooking vessel being a non-magnetic type of cooking vessel, set the operating frequency of the inverter to a value that is less than a second resonate frequency.

An induction heating-type cooktop comprising:
- a working coil configured to heat a cooking vessel;
- an inverter configured to supply current to the working coil, the inverter including a plurality of switching elements;
- and
- a controller configured to:
- in response to the cooking vessel being a magnetic type of cooking vessel, adjust a heating output of the induction heating-type cooktop by varying an operating frequency of the inverter;
- and
- in response to the cooking vessel being a non-magnetic type of cooking vessel, adjust the heating output of the induction heating-type cooktop by changing a duty cycle of one or more switching elements among the plurality of switching elements.
