The three-phase AC photovoltaic water pump is the research object, and the mathematical model of the photovoltaic system, the maximum power point tracking method, the three-phase inverter voltage modulation strategy, the photovoltaic water pump system topology and control strategy, and the software and hardware design of the photovoltaic water pump controller are carried out in-depth Research. Based on the steady-state mathematical model of the asynchronous motor, the mathematical model of each module of the photovoltaic system is established, and a simplified photovoltaic water pump model is proposed. In order to further improve the performance of the photovoltaic water pump system, as well as the system structure to control strategy, reduce Cost, efficiency improvement, maximum power tracking and other aspects provide effective theoretical support. In-depth study of the control strategy of photovoltaic water pumps, and proposed a single-chip microcomputer-based direct digital synthesis of the same voltage space vector pulse width modulation algorithm.
