Abstract: The present invention relates to a method for controlling an inverter of an eco-friendly vehicle to reduce noise, and more specifically, the purpose of which is to provide a method capable of reducing noise caused by a switching frequency of an inverter by changing the frequency range of generated noise according to the inverter switching frequency of an eco-friendly vehicle. To this end, the method for controlling an inverter of an eco-friendly vehicle to reduce noise comprises the steps of: monitoring a current motor torque and a current motor speed in real time; determining whether or not the current motor torque and the current motor speed corresponds to a noise occurrence range set to a current switching frequency; calculating a changed switching frequency value corresponding to the current motor torque and the current motor speed if it is determined that the current motor torque and the current motor speed corresponds to the noise occurrence range; and generating a pulse width modulation (PWM) signal using the changed switching frequency value to control the inverter.
