摘要：
A novel high-frequency isolated grid-connected PV inverter based on sinusoidal pulse width position modulation (SPWPM) is studied. It is suitable for household PV utility with advantages of light weight, small volume and high efficiency. The working principle is analyzed in details and a close loop control strategy is designed. In order to eliminate the gridconnected current distortion caused by phase error, the phase compensation control strategy is employed in current control loop to improve the traditional proportional integration controller. Validity of the topology and control strategy of this novel inverter is verified with experimental results.
