A new control scheme for three-phase four-leg inverter
In the unbalanced or non-linear load conditions, the ordinary three-phase three-leg inverter can not produce three-phase symmetrical voltage, based on the Simulink simulation platform, this paper presents a new closed-loop control design scheme for three-phase four-leg inverter. In this scheme, the...

| description | In the unbalanced or non-linear load conditions, the ordinary three-phase three-leg inverter can not produce three-phase symmetrical voltage, based on the Simulink simulation platform, this paper presents a new closed-loop control design scheme for three-phase four-leg inverter. In this scheme, the first three arms of the inverter adopt space vector pulse width modulation(SVPWM), the fourth bridge uses the current hysteresis loop modulation(CHBM) to track three-phase current signal. Compared with the traditional four-leg integrated SVPWM modulation, the control system is simple and easy to analyze. The simulation results show that compared with the ordinary inverter, the waveform of the four-leg inverter with the control scheme is smoother, which not only enhances the ability of the system with unbalanced load, but also improves the inverter system efficiency and total harmonic distortion(THD). |
