Abstract: The present disclosure relates to a power converting device and a home appliance including the same. A power converting device according to an embodiment of the present disclosure comprises a first capacitor, a first switching element turned on to output a first voltage stored in the first capacitor to a first node which is one end of an inductive load, a second switching element, one end of which is connected to the first switching element and which is turned on to decrease the voltage of the first node to the first voltage, a third switching element turned on to output a second voltage greater than the first voltage to the first node which is one end of the inductive load, and a fourth switching element, one end of which is connected to the third switching element and which is turned on to decrease the voltage of the first node to the ground voltage. Accordingly, switching loss may be reduced when power is supplied to an inductive load.
