How to maximize the energy generated by photovoltaic cells. Since the output power of the PV cell is a nonlinear function that is affected by the intensity of sunlight and ambient temperature, the output power of the PV cell will vary with the external load even when the external environment is stable. Therefore, in order to maximize the energy generated by the photovoltaic cells, it is necessary to use the maximum power point tracking circuit between the photovoltaic cell and the load.

② how to get a relatively stable DC link voltage. In order to reduce the voltage level of the inverter, the cost, weight and volume of the prototype and the system are reduced, and the mutual influence between the photovoltaic cell and the power grid must be reduced. In addition, the voltage fluctuation range of the PV cell is very large. Of the power adjustment circuit.
