The present disclosure relates to an induction heating apparatus and a method for controlling the same. In one embodiment, when a power level of a heating zone is input, a noise suppressing operation may be performed to suppress initial driving noise that might occur before a frequency for heating a container. A controller of the induction heating apparatus may adjust duty cycles of switching signals input to switching elements included in an inverter circuit and a driving frequency of the inverter circuit respectively and perform the noise suppressing operation. In the embodiment, when a power level of a heating zone is set and a container starts to be heated, initial driving noise may be reduced.
