Abstract

There is provided methods and systems for balancing junction temperatures between at least two power switches of a multilevel converter. A junction temperature of each of the at least two power switches is received. A difference in junction temperature between the at least two power switches is determined. A ratio of operating time for which the multilevel converter operates using a first pulse width modulation, PWM, mode of a plurality of PWM modes is defined based on closed loop control in order to reduce the difference in junction temperature of the at least two power switches. Finally, a control signal is generated to operate the multilevel converter using the first PWM mode for the ratio of operating time.
