DC Link Capacitor Voltage Balancing Method for Diode-Clamped Multilevel Converters
2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019This paper proposes a new capacitor voltage balancing method for diode-clamped multilevel inverters. In this method, proper redundant switching state is selected according to clamp points' voltages. The proposed method is independent of the phase and level numbers and is computationally optimized for practical implementation.

Voltage-balance limits in four-level diode-clamped converters with passive front ends
IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003Multilevel diode-clamped converters with more than three levels cannot maintain voltage balance in the dc-link capacitors for some operating conditions due to the existence of dc currents in the middle points. Since capacitors are either completely charged or discharged for those conditions, this circumstance severely limits practical application of ...

A new balancing technique with power losses minimization in Diode-Clamped Multilevel Converters
2007 European Conference on Power Electronics and Applications, 2007A new PWM technique, capable of achieving a correct dc-link capacitor voltages balance in Diode- Clamped Multilevel inverters, within the limits defined by the theory, is presented. This result is obtained while decreasing the switching power losses when compared to techniques based on the use of redundant switching vectors.

A Novel Hybrid Voltage Balance Method for Five-Level Diode-Clamped Converters
IEEE Transactions on Industrial Electronics, 2018Voltage balance control of dc capacitors is the key problem of multilevel diode-clamped converters (DCCs). In this paper, a novel hybrid voltage balance method is proposed for five-level DCCs. First, to balance the upper or lower two capacitors, a novel flying-capacitor-based voltage balance circuit (VBC) is proposed, and the time-domain average model ...
