Abstract
Disclosed herein are a power converting apparatus and a home appliance having the same. The power converting apparatus according to an embodiment of the present invention includes an inverter having a plurality of upper switching devices and a plurality of lower switching devices, a plurality of upper gate drivers to output a gate drive signal to each of gate terminals of the plurality of upper switching devices, and a plurality of upper ON resistors disposed between the plurality of upper switching devices and the plurality of upper gate drivers, wherein resistance values of the upper ON resistors are different from each other. Thus, electromagnetic interference noise generated when the inverter is turned on or off may be attenuated without changing the switching frequency.
