Taking into consideration the disadvantages of the serial structure controller-slow operation speed, poor grid current quality for the present grid-connected invert, the authors proposed a new grid-connected invert architecture, which ACN is based on SOPC control technology on FPGA platform.It adopts the direct current PI control strategy with grid voltage feed-forward and uses hardware to realize algorithm, which improved the running speed and the overall performance of system.Meanwhile, designed regulator parameters for the control strategy and constructed grid-connected control system IP hard core for the invert in this paper.Experimental results of 1 kW prototype show that this method has good grid Axe Accessories current quality and strong synchronous tracking capability.
