Abstract	本申请提供了一种充电电路与充电系统，涉及充电技术领域。该充电电路包括第一开关管、第一电容、基准电压源以及至少两个降压模块，至少两个降压模块依次电连接，第一开关管分别与第一个降压模块、第一电容电连接，第一电容也与第一个降压模块电连接，最后一个降压模块分别与基准电压源、输出端口电连接，且每个降压模块均包括第二电容；其中，当充电电路处于第一状态时，第一电容与每个降压模块中的第二电容串联，并对第一电容与第二电容充电；当充电电路处于第二状态时，第一电容与每个降压模块中的第二电容并联，并通过第一电容与第二电容对输出端口进行放电。本申请具有能够实现更高倍数的电压电流变化的优点。
Other Abstract	The invention provides a charging circuit and a charging system, and relates to the technical field of charging. The charging circuit comprises a first switch tube, a first capacitor, a reference voltage source and at least two voltage reduction modules, the at least two voltage reduction modules are electrically connected in sequence, the first switch tube is electrically connected with the first voltage reduction module and the first capacitor, and the first capacitor is electrically connected with the first voltage reduction module. The last step-down module is electrically connected with the reference voltage source and the output port, and each step-down module comprises a second capacitor; when the charging circuit is in a first state, the first capacitor is connected in series with the second capacitor in each step-down module, and the first capacitor and the second capacitor are charged. And when the charging circuit is in a second state, the first capacitor is connected in parallel with the second capacitor in each step-down module, and the output port is discharged through the first capacitor and the second capacitor. The method has the advantage that voltage and current changes with higher multiples can be achieved.
