摘要
采用安森美公司的电流控制型脉宽调制芯片UC3842为一款1 kW铅酸蓄电池充电器控制电路设计了输出功率为25 W的辅助电源。根据文献[5]设计了UC3842的外围电路,分析了输出反馈控制回路用元器件参数的计算方法,并结合给定功率场效应管最大耐压值设计了反激式高频变压器,最后将按照设计参数制作的样机安装到充电器控制板上,充电器在满载状态下工作稳定。实验结果表明:样机工作稳定可靠,具有良好的静态特性和动态特性。
In this paper,a 25 W auxiliary power supply was designed with current control type chip-PWM IC UC3842 made by Ansenmei Co.for the control circuit of 1 kW lead-acid battery charger.The external circuit of UC3842 was designed according to [5].The calculating method of component parameters used in output feedback control loop was analyzed and a flyback high frequency transformer in accordance with the maximumVdsof MOSFET was designed.Finally,the test data verified that this prototype 1kW charger could work stably under full load.
