Voltage imbalance poses a challenge to photovoltaic systems. A modular structure based on
a three-level boost converter is proposed to address this problem. The three-level boost …

The short circuit fault in the voltage source converter-based dc power system typically
generates rapidly rising transient current which may have serious repercussions on dc grid …

Asynchronous interconnection of grids has advantage over synchronous interconnection in
terms of fault clearance time, islanding operation and disturbance propagation. Presently …

This article presents a new three-phase five-level converter topology with a single dc source.
The proposed topology combines the features of the conventional flying capacitor multicell …

A new nine level inverter is presented in this paper. It combines PUC and NPC topologies to
create a new competitive converter that makes use of small count of power devices to …

Asynchronous micro-grid power conditioning system (AMPCS) had been proposed for
integrating two medium voltage nonsynchronous grids. Neutral point clamped (NPC) …

To balance dc voltage, a two-module structure based on a dc–dc three-level boost converter
is utilized. In this article, the possible operating modes for a two-module converter in the …

In this paper, a novel PWM technique insuring the self-balancing of the capacitors voltages
has been proposed for the attained nine-level packed U cells (PUC) converter. In the …

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 …

The use of series connected IGBTs is still a current subject in literature, despite such a
discussion having started in the 1990s. Though countless academic studies, there are …
