Full bridge structure is adopted in the backend inverter circuit. In order to realise the balanced flow of power, to improve the system's response speed and to eliminate the influence of the resonance peak of LCL filter, the three loop control strategy is adopted in the inverter system. At the same time, the reason of generation of the dead-time and its influence on the output of the grid-connected inverter are analysed in detail. And an improved dead-time compensation method is proposed for zero-current clamping phenomenon. The output voltage error of inverter is extended from two to seven in this method, which effectively solves the problems, such as zero-crossing distortion of the grid-connected current, additional odd harmonic content, higher distortion rate and lower amplitude of fundamental wave.Keywords: grid-connected inverter; dead-time compensation; PV.
