New Nine-Level Inverter with Self Balancing of Capacitors Voltages

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
In this paper, authors propose a hysteresis controller insuring the self balancing of the capacitors voltages without using any voltage sensor. Capacitors voltages of the fifteen-level PUC inverter have to be maintained around their references using a state variable feedback which requires three sensors, two for the capacitors voltages and one for the ...

Capacitor Voltage-Balancing Techniques for a Multipulse Rectifier With Active Injection

IEEE Transactions on Industry Applications, 2009
Two techniques are presented to balance the filter capacitor voltages of a multi-pulse rectifier with active injection operating on a variable frequency supply. The active injector consists of a low-rated, bidirectional switch that modifies the behaviour of a 12-pulse rectifier at either low or high-frequency , resulting in 24-pulse or multi-level PWM ...

Capacitor Voltage Balancing in Multi-Level Voltage Reinjection (MLVR) Converters

IEEE Transactions on Power Delivery, 2005
In common with conventional multi-level conversion configurations, the multi-level voltage reinjection scheme uses multi-level clamping and dc series connected capacitors. The operation conditions that lead to capacitor voltage unbalance are analyzed and the use of adaptive adjustment of the clamping switches conducting periods is investigated.

Capacitor Voltage Balancing of Flying Capacitor Multilevel Converters by Space Vector PWM

IEEE Transactions on Power Delivery, 2012
Proper operation of a multilevel flying capacitor converter (FCC) necessitates a closed-loop voltage balancing strategy. This paper proposes a space vector modulation (SVM)-based approach that benefits from the switching state redundancy of an n-level FCC to implicitly carry out the voltage balancing task within the switching strategy.
