An Interline Dynamic Voltage Restorer Using Neutral-Point-Clamped (NPC) Multilevel Converter
Because of increased number of sensitive loads and automated processes in industry, need for high quality power is nowadays inevitable. Deteriorated power quality my result in huge financial losses and also decreases the productivity. The power electronic based solutions for improving power quality have become more common in the recent years.

We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.

Active Voltage Balancing Control of 9‐Level Multicell‐Based A‐NPC Inverters
We present a optimization‐free PWM control for single‐phase 9‐level FC A‐NPC inverters that converts measured current and capacitor voltages into logic equations to both balance FC voltages and generate the commanded levels. By removing objective functions/optimizers, it enables fast, simple implementation, with experiments showing robust performance ...

A Harmonic Voltage Injection Based DC-Link Imbalance Compensation Technique for Single-Phase Three-Level Neutral-Point-Clamped (NPC) Inverters [PDF]
In three-level neutral-point-clamped (NPC) inverters, the voltage imbalance problem between the upper and lower dc-link capacitors is one of the major concerns. This paper proposed a dc-link capacitor voltage balancing method where a common offset voltage was injected.
