| Abstract: | A single-phase PV(PhotoVoltaic) grid-connection control scheme based on DSP and FPGA(Field-Programmable Gate Array) is proposed.The DSP is responsible for the voltage-frequency-conversion-based high-accuracy data acquisition,MPPT(Maximum Power Point Tracking) and voltage control loop.It transmits the calculated MPPT current to FPGA via serial peripheral interface.FPGA is responsible for the grid-voltage digital phase-locked loop,current deadbeat control and SPWM drive algorithm.It controls the on-off of inv... |
