In flexible interconnection systems of distribution networks

common-mode voltage generated by power electronic converters may lead to a series of adverse issues such as leakage currents. The reduced common-mode voltage pulse width modulation (RCMV-PWM) techniques are widely studied and emphasized to deal with the problem. In four-wire systems

two-level four-leg RCMV-PWM often involves simultaneous switching actions of two different bridge arms. In such cases

the dead-time effect of interlocked switching devices may introduce undesired common-mode voltage spikes

increasing residual common-mode voltage and weakening the suppression effect. This paper proposes a modified active-zero-state PWM (AZSPWM) method based on current prediction and active disturbance dead-time compensation

which effectively reduces residual common-mode voltage and improves power quality. The paper presents a prediction method for the converter output current

achieving dead-time compensation by adjusting the amplitude of the modulation wave. Furthermore

to address the inaccuracy of current direction prediction near zero-crossing points

this paper introduces an active disturbance control method to regulate the current direction and enhance prediction accuracy. Simulation and experimental results verify the effectiveness of the proposed method.
