电源技术  逆变电路的基本工作原理

单相桥式逆变电路为例：S1～S4是桥式电路的4个臂，由电力电子器件及辅助电路组成。S1、S4闭合，S2、S3断开时，负载电压uo为正S1；S1、S4断开，S2、S3闭合时，uo为负，把直流电变成了交流电。改变两组开关切换频率，可改变输出交流电频率。图5-1 逆变电路及其波形举例电阻负载时，负载电流io和uo的波形相同，相位也相同。阻 ...

单片机编程  NXP P89LPC901单片机汽车起动保护控制器设计

在汽车发动机起动时，若发动机起动后起动机不能及时断电，将会烧毁起动机或损坏飞轮齿环；若变速器不在空档位置起动，则起动机的瞬间动力将使汽车位移，还可能引起交通事故和人身安全。为此介绍一种利用NXP P89LPC901单片机控制的汽车起动保护控制器，通过检测汽车起动开关、变速箱档位、发动机转速，实现对汽车发动机起动 ...
