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 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 BOSCH GUD15AFF0G Integrated Undercounter Freezer 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 LC of 1 kW prototype show that this method has good grid current quality and strong synchronous tracking capability.
