Circuits and methods for power conversion
Abstract:
A power conversion circuit includes a solar panel and a power converter. The solar panel is operable for providing electric power having an output voltage. The power converter coupled to the solar panel is capable of selectively operating in a charging mode and a powering mode. The power converter transfers the electric power from the solar panel to a power source and maintains the output voltage at a threshold voltage in the charging mode. The power converter delivers power from the power source to a load in the powering mode.
Abstract(Chinese):

电力转换电路包括太阳能电池板和电力转换器。 太阳能电池板可操作用于提供具有输出电压的电力。 耦合到太阳能电池板的功率转换器能够以充电模式和供电模式选择性地工作。 功率转换器将电力从太阳能电池板传送到电源，并将充电模式下的输出电压维持在阈值电压。 电源转换器在供电模式下将电源从电源传输到负载。
