Abstract

Based on the analysis of dead zone compensation principle in H-bridge inverter series structure, an improved average voltage feedforward compensation method of H-bridge inverter series structure is studied. Because the traditional average voltage feedforward compensation method has the phenomenon of false compensation in the current zero crossing region, the zero crossing region of the H-bridge inverter series structure output current is precisely divided in the improved method. Outside the current zero-crossing region, adopting the average voltage feedforward method. During the current zero-crossing region, the dead zone will not affect the output voltage, so no compensation is required, which effectively avoid the traditional average voltage feedforward compensation method has the phenomenon of false compensation caused by misjudgment of current direction in zero crossing region. Finally, the improved dead zone compensation method of H-bridge inverter series structure is simulated by MATLAB/SIMULINK software. The results verify the effectiveness of the method.
