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i...
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...
