Active DC Voltage Balancing PWM Technique for High-Power

Cascaded Multilevel Converters

ABSTRACT

In this paper, a dedicated pulse width modulation (PWM) technique specifically

designed for single-phase (or four wire three-phase) multilevel Cascaded H-Bridge Converters is

presented. In recent years multilevel converters have been identified as a favored topology for

high power applications as a result of advantages such as high levels of modularity, availability,

overall efficiency, and high output waveform quality. This is achieved at the expense of

increased numbers of components and control complexity. In all the aforementioned

applications, multilevel converters are being increasingly considered as a fundamental

technology, as a result of their capability to handle high-power, utilizing low voltage power

devices, while maintaining superior quality output waveforms, even at low device switching

frequency.

Among all the possible multilevel converter topologies Cascaded H-Bridge converters

(CHB) represent an interesting solution in several applications where its reduced number of

components when compared to other multilevel converter topologies and high modularity are

important features which lend themselves to the improvement of overall system efficiency and

reliability. The main issues with the CHB converter is the requirement for isolated DC-Link

voltages as well as the significant effect of device voltage drop and on-state resistance in

applications with high number of levels and relatively low application ac side voltages In this

paper, the latter case is considered and a novel modulation technique, developed for single-phase

systems and suitable for high power multilevel CHB converters, is introduced. The proposed

modulation strategy is based on the Distributed Commutation Modulator (DCM).
