Disclosed is a device for measuring a temperature of an inverter. The device for measuring the temperature of the inverter of the present invention comprises: a variable resistance whose resistance value changes in accordance with a temperature of the inverter; a plurality of distribution resistances having one side connected in series with the variable resistance; a switching part for applying power to at least one of the distribution resistances; an AD converter which receives a voltage distributed by the distribution resistance and the variable resistance and converting the voltage into a digital signal; and an MCU which controls the switching part to supply power to any one of the distribution resistance, and detects a temperature of the inverter by using the signal converted by the AD converter.

    인버터 온도 측정 장치가 개시된다. 본 발명의 인버터 온도 측정 장치는 인버터의 온도에 따라 저항값이 변하는 가변저항; 일측이 가변저항과 직렬 연결되는 복수 개의 분배저항; 분배저항 중 적어도 하나에 전원을 인가하는 스위칭부; 분배저항과 가변저항에 의해 분배된 전압을 입력받아 디지털 신호로 변환하는 AD 컨버터; 및 스위칭부를 제어하여 분배저항 중 어느 하나로 전원을 인가하고, AD 컨버터에 의해 변환된 신호를 이용하여 인버터의 온도를 검출하는 MCU를 포함하는 것을 특징으로 한다.
