A novel voltage balancing control method for flying capacitor multilevel converters
IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468), 2004The voltage unbalancing issue remains a challenge for the multilevel flying capacitor (FC) converter. It becomes more prominent when the number of levels of the converter is higher than three which needs to be addressed. The phase-shifted sinusoidal PWM (PS-SPWM) method has a certain degree of self-balancing characteristic in the ideal symmetrical ...

An improved capacitor voltage balance control for cascaded H-bridge rectifier
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014The cascaded H-bridge rectifier (CHBR) is widely used in high voltage and high power applications. Due to switch in/out of H-bridge module frequently, the problem of traditional CHBR is the high switch frequency and great switch power loss of semiconductor devices.
