A fairly basic circuit (left as an exercise, but it's not difficult) can take the control voltage and output a constant current which is proportional to the voltage.

一个相当基础的电路(留作练习，不过并不难)处理控制电压并输出与电压成比例的恒流。

Comparing to conventional fixed voltage, the slope limit voltage in the over power protect circuit can improve the constant power limit capability in different input voltage.

提出在过功率保护电路中利用斜坡电压取代传统的固定电压，以达到不同输入电压下的恒定功率限制。

Two charge ways are commonly taken in charge circuit, charge with constant voltage and charge with constant current.

一般的充电回路采用的充电方式有两种：恒压充电和恒流充电。
