| Abstract: | The design of intelligent current source with closed loop is presented in this paper. The system core is the MCU. The closed loop control and PID arithmetic is used to realize high precision and wide range. The intelligent current source realizes that the output current can be pre-set, adjusted step by step and displayed in digit directly. Above functions are operated by serial communication port between PC and the MCU, or keyboard within the current source. The stability of this current source is hight and its loading capacity is strong. It offers qualification for automatic measurement of experiment teaching. |
