摘要:
摘要:根据Boost电路的特点,设计一种基于Boost 结构的开关电源。讨论电路的电流连续工作模式,设计了电源的脉宽调制(PWM)电路和过流保护电路,并给出了蓄能电感、输出电容和输出电压取样电阻的确定方法。最后对设计的电源性能进行了测试和分析,测试结果表明该电路转换效率较高而且工作非常稳定。
Abstract:
Abstract: Based on the property of boost converter, a switch power based on boost converter is designed in this paper. And then, the contiunous current mode (CCM)of this circuit is discussed, and the PWM circuit and over-current -protection circuit are designed. At the same time, the calculation methods of storage inductance, output capacitor and sampling resistor are given. Finally, the property of the designed power supply is tested and analyzed. The test results show that the system has not only high conversion efficiency, but also high stability.
