Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0033] refer to Figure 1-2 : Solar DC step-up regulated charging power supply, including sequentially connected solar cells, battery packs, power shortage protection circuit, adjustable square wave circuit, DC boost circuit, and DC adjustable voltage stabilizing circuit;
[0034]The solar battery V1 is used for photoelectric conversion, and the electric energy converted by the solar battery V1 is used to charge the battery pack V2. The charging line of the solar battery V1 to the battery pack V2 is connected with a first diode D1 to prevent reverse charging of electric energy. The positive pole of a diode D1 is connected to the positive pole of the solar battery V1, and the negative pole of the first diode D1 is connected to the positive pole of the battery pack V2, the nominal voltage of the battery pack V2 is 6V;
[0035] The power-shortage protectio...
