Modulated Model Predictive Current Control of a Four-Leg Inverter
2020 11th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC), 2020A novel modulated model predictive current control for a two-level four-leg voltage source inverter is proposed in this paper. The proposed scheme is designed by combining the operating principles of traditional predictive control with the three-dimensional space vector modulation to enhance the output power quality, while producing fixed switching ...

Transient Operation of a Four-Leg Inverter for Autonomous Applications With Unbalanced Load
IEEE Transactions on Power Electronics, 2010In this paper, the transient operation of a four-leg inverter equipped with an innovative control strategy under unbalanced load conditions is investigated. The inverter is proposed for transformerless hybrid power system applications, in order to provide simultaneous supply of three-phase and single-phase AC loads with balanced voltage and constant ...

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.

Characteristics of Switched Reluctance Motor Driven by Four-Leg Inverter Applied with PWM Control
Annual Conference of the IEEE Industrial Electronics Society, 2023Switched reluctance motors (SRMs) are attractive due to their low cost and robustness because it does not require rare earth materials. Asymmetric H-bridge inverters (AHBIs) are commonly used as a drive circuit for SRMs.

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 ...
