Switching-Cell Four-Leg Current Source Inverter
IEEE Transactions on Industrial Electronics, 2021Conventional current source inverter (CSI) suffers from open-circuit problem during switch transition. Thus, overlap-time should be inserted in the gate signals for safe commutation. The overlap-time distorts output current waveforms and increases total harmonic distortion of output current.

2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013
A novel dual-output four-leg inverter topology is proposed in this paper. The proposed inverter which is able to provide two three-phase voltage sets of independent magnitudes and frequencies is operationally equivalent to two four-leg inverters working independently though with a reduced number of semiconductor switches and hence gate drive and ...

A new 3D-SVPWM algorithm for four-leg inverters
2009 IEEE International Electric Machines and Drives Conference, 2009A new algorithm of tetrahedron determination applied to the SVPWM control of four leg inverters is presented in this work. Indeed during the last years two main families of works were existing under this subject, the first one used the αβγ frame , while, the second one used the abc frame.

Predictive Duty Cycle Control for Four-Leg Inverters With ${LC}$ Output Filter
IEEE Transactions on Industrial Electronics, 2021Three-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), 2012Four-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, 2013This 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.
