摘要
本文提出了一种农用车载蓄电池自动充电电源,阐述了变换电路的工作过程,以电流型PWM芯片UC3846作为电流/电压调节器,并分析了控制系统工作原理。该电源为恒流—恒压输出特性,适用于作蓄电池充电器。最后给出了此充电电源的主电路实验波形。
An automatic portable battery power supply on agricultural vehicle is introduced in this paper. The main inverter circuit is discussed. The current PWM UC3846 is used as a current-voltage regulator in the power supply. At the same time, the principle of control system is taken out in this paper. The Bower suoolv has steady current -steady voltage outout characteristics, and it is fit for battery charger. Finally the experimental waveform of the main circuit is given.
