ABSTRACT = {With the spreading of Photovoltaic (PV) grid-connected system, grid-connected 
reactive-load compensation and harmonic control is becoming a research focus. 
Unipolar and bipolar modulations are widely used in active power filter of PV 
grid-connected inverter. Unipolar modulation is good at harmonic, ripples and 
efficiency control, while bipolar modulation is good at grid-connected current 
control. A comprehensive comparison between the aforementioned modulation
strategies in aspects of basic switching action, effects on operation mode, 
current harmonics，efficiency, is done in this paper. Base on it, a hybrid 
modulation strategy with the fusion of the unipolar and bipolar modulation is 
proposed in this paper. Numerical and experimental results show the lowest 
total harmonic distortion, and enhanced zero passage control are achieved by 
the proposed method, providing a reliable and efficient control strategy for PV 
grid connecting.},
