Disturbance observer-based composite voltage synchronisation control of three-phase four-leg inverter under load variation

International Journal of Control, 2021
The three-phase four-leg inverter is widely used in microgrid recently. The control strategy is critical for the performance of nonlinear four-leg inverter system owing to the problems of coupling, disturbances of nonlinear/unbalanced loads, variable ...

Predictive Duty Cycle Control for Four-Leg Inverters With ${LC}$ Output Filter

IEEE Transactions on Industrial Electronics, 2021
Three-phase four-leg inverter is a well-known solution to handle unbalanced and nonlinear loading conditions in three-phase transformerless uninterruptible power supply applications. For such power converters, finite control set model predictive control (FCS-MPC) is considered as a promising control alternative due to its simplicity, fast dynamic ...

Control methods for four-leg voltage source inverter

2012 International Conference on Devices, Circuits and Systems (ICDCS), 2012
Four-leg voltage source inverters are more advantageous than 3-leg voltage source inverters in such a way by the greater utilization of DC link voltage, independency of the modulation factor of load current and avoidance of superposition of a DC component with the AC output voltage. Four-leg voltage source inverters require a balanced sinusoidal output

Carrier-based PWM scheme for three-phase four-leg inverters

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
This paper presents a pulse-width modulation (PWM) technique for controlling three-phase, four wire voltage source inverters (VSI). It is an extended scheme of a digital scalar pulse width modulation previously proposed for controlling three-leg inverters.

Modified selective harmonic elimination employed in four-leg NPC inverters

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
Three-phase four-leg neutral point clamped (NPC) inverter is more suitable in dealing with all sort of the loads especially unbalanced/nonlinear due to harmonics issues. Most control strategies applied on four-leg NPC are classified as high switching frequency lead to high power losses and low efficiency.
