Based on tms320f28027 DSP platform, the simulation device of photovoltaic grid connected power generation is made and tested. This design uses tms320f28027dsp as the control chip to make a single-stage photovoltaic grid connected simulation device. This device adopts voltage type full bridge as the main circuit topology, uses software phase locked loop technology for output phase tracking control, and uses disturbance observation method to realize maximum power point tracking control.
