摘要
以C8051F410型单片机最小系统为控制核心,采用半桥全波式DC/DC变换电路,基于TL494芯片调制脉宽,设计了一套开关电源模块并联供电系统。通过关键性能指标测试,确认该系统输出电压稳定,输出电流可按任意设定比例分配,供电效率、短路保护阈值电流、最大纹波电压等参数均良好。
A parallel operation system with switching power supply modules was designed hy taking the minimum system of CS051F-110 microcontroller as the core for control and adopting full- wave half-bridge DC/DC converter and based on TL494 chip for pulse width modulation. By testing its key performance indicators it is found that the output voltage of the system is stable , the output current can he set at any proportional distribution, its supply efficiency, short circuit protection, threshold current and maximum ripple vohage and other parameters are excellcnt.
