Quasi Two-level Operation of a Five-level Inverter

2007 Compatibility in Power Electronics, 2007
In this paper a five-level inverter operational mode termed quasi two-level operation is proposed. The multilevel capacitors function in a soft clamping mode where capacitor voltage balancing is maintained by varying the transient dwell time at each level. Two balancing techniques are proposed.

A Five-Level Boosting Inverter for PV Application

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
Transformerless inverters (TIs) are widely used in grid-connected photovoltaic (PV) applications due to their higher efficiency and low cost. However, the absence of galvanic isolation leads to the flow of ground leakage current due to PV parasitics resulting in safety issues and deteriorated power quality.

Control Methods for Five Level Inverter

2019 15th International Conference on Engineering of Modern Electric Systems (EMES), 2019
In this paper are presented two control methods for single-phase five level inverter: staircase modulation (SM) and pulse width modulation (PWM). In both cases the switching sequences have been chosen so that the number of semiconductor devices which switch at a certain time to be minimal. For the PWM modulation, it has been studied how the arrangement
