摘要：
For the two stage neutral point clamped three level photovoltaic inverter generation system, the output features of solar cells are analyzed, and the SVPWM control scheme under the 60 DEG coordinate system is analyzed and selected. The control strategy and photovoltaic cell MITT are simulated using Matlah/Simulink, show the good effect of the control system. Build the experimental hardy are platform of DSP+FPGA based on double CPU, the system has a good tracking performance of the power grid voltage, and the system has a fast dynamic response, the output-current sine degree, low total harmonic distortion and realize the unit power factor operation.
