Claim 12:
13. An induction heating apparatus comprising:
a heating coil configured to heat a container and comprising:
a first heating coil,
a second heating coil, and
an intermediate point to which the first heating coil and the second heating coil are connected;

an inverter provided in a form of a full bridge in which a first arm and a second arm are connected in parallel, wherein each of the first arm and the second arm comprises two switching elements connected in series;
a capacitor provided between an end of the first heating coil and a first node of the first arm of the inverter, the first node is an intermediate node arranged between the switching elements of the first arm;
a first relay provided between a second node of the second arm of the inverter and an end of the second heating coil, the end of the second heating coil is on the opposite side of the intermediate point to which the first heating coil and the second heating coil are connected;
a second relay provided between the second node of the inverter and the intermediate point of the heating coil; and
a processor configured to:
detect a presence or an absence of the container on the heating coil, based on an output current of the inverter, and
open one of the first relay and the second relay and close the other of the first relay and the second relay based on a detection result of the container.
