Balancing capacitively split DC link of three-level inverters

Abstract

Nowadays, electric vehicles are playing an increasingly important role in transport. In everyday life, this is most evident in passenger cars, but at the same time, there are huge advances in freight transport and aviation. In order to maintain this developing trend, developers are striving to achieve the highest possible power density and maximum efficiency. With this increased efficiency comes longer driving range, thus electric car industry could take a bigger slice of the urban commuter traffic.
