Provided is a power conversion device on which an IGBT power module that includes a main IGBT and a current sense IGBT in the same semiconductor chip is mounted, wherein the power conversion device is a high-performance and highly reliable power conversion device capable of accurately estimating a main current flowing through the main IGBT using a sense current in an entire operation region of the power conversion device. A power conversion device includes: a first IGBT through which a main current flows; a second IGBT which is disposed on the same semiconductor substrate as the first IGBT and through which a sense current flows; and a measurement device which calculates the main current based on the sense current, wherein the measurement device selects a method of calculating the main current corresponding to a current value of the sense current.
A power conversion device comprising:
A method of controlling a power conversion device on which an IGBT power module which includes a main IGBT and a current sense IGBT are mounted on a same semiconductor chip, the method comprising the steps of:
