Description: The Simulink topology of the main circuit and the control circuit of the single-phase inverter grid connected circuit,
The main circuit is composed of DC source, MOSFET full bridge, LC passive filter, load R1 and R2, wherein R1 is
The constant load, R2, is incorporated into the simulation load mutation.
The control circuit is SPWM closed loop modulation, and the effective value of the output voltage is detected through the PI controller
The feed back control makes the output voltage as high as possible a sine wave, and the effective value is about 220V, frequency
For 50Hz, the output voltage waveform THD shall be within 5%, according to the relevant guidelines.
