title = "Modulation strategy for highly reliable cascade H-Bridge inverter based on discontinuous PWM",
abstract = "The Cascaded H-Bridge (CHB) topology is widely employed in high power and high voltage applications due to advantages of the low dv/dt, the low EMI noise, and the low filter inductance. An issue of this modular system is the possible unequal thermal stress of the power semiconductors in the cells, which is affecting the reliability and leads to maintenance costs and down-times. In this paper, the seven-level CHB topology is considered and the modulation strategy based on the Discontinuous PWM (DPWM) is proposed to improve the reliability by reducing the switching losses of a cell experiencing premature wear-out.",
