In my paper, the design concept is to achieve a SOPC system based on FPGA to control the Grid-Connected by Inverter with the SPWM control signal which can get more improvement.I use the SPWM technique to adjust the DC/AC inverter output voltage amplitude and frequency to the desired value. my design of SPWM generator is capable to operate at switching frequencies up to higher frequencies, thus it is capable to support the high switching frequency requirements of DC/AC power converters. my design achieves a SOPC system which is possible to consider design strategies that use both software and hardware compared with traditional controller.
