摘要： An induction cooker includes a rectifying device, a first energy-storage device, a switch device, a second energy-storage device, a heating device and a control device. The capacitance of the second energy-storage device is greater than the capacitance of the first energy-storage device. When the induction cooker is just starting, the control device controls the switch device to be turned off, such that the heating device generates an output current according to an energy of the first energy-storage device. The control device determines whether a pot is on the heating device according to a change state of the output current. When the pot is on the heating device, the control device controls the switch device to be turned on, such that the first and second energy-storage devices are coupled, and the heating device heats the pot according to energies of the first and second energy-storage devices.
