The integrated single-tube DC/DC converter for photovoltaic battery-powered water pump systems, including photovoltaic cells, batteries, water pump systems, and DC/DC converter circuits. The DC/DC converter circuit includes the previous Buck circuit and the subsequent switching inductor The high-gain BuckBoost circuit, the front-end circuit and the back-end circuit are connected with the switch tube S. The front-end circuit of the converter works in DCM mode, and adopts variable frequency control to realize the free switching of MPPT and battery constant voltage charging dual mode to improve solar energy Utilization rate and realize the overvoltage protection of the battery; the back stage circuit works in the CCM mode, and adopts variable duty cycle control to realize the step-down speed regulation of the water pump. The converter of the present invention uses the switch tube to reuse the front stage Buck converter Integrated with the back-stage switching inductor BuckBoost converter, it has the advantages of simple structure, low cost, wide output voltage adjustment range, and high efficiency.
