积分:131448 版主 | | | 这是如何调制出来的?调制频率多少?输出频率多少?是用的啥样的电路? |

|
| | | | | | | | | | | 就是之前的那个IRFP460电路,不同频率下波形差不多都是这个样子 |

|
| | | | | | | | | | | | | | | 输出线套一个电流互感器,电流互感器串上一个电阻接地,示波器测的就是这个接地电阻两端的电压,反映的是线上的电流 |

积分:131448 版主 | | | | | | | | | 现在板上的桥边装的+-电源线上的电容多大?每半桥几个? |
|
|
| | | | | | | | | | | | | | | | | | | 300V电源和地之间是18个220U/400V的电解 |

积分:131448 版主 | | | | | | | | | | | 是不是每半桥就近没装电容?(紧挨FET管脚装焊的电容)。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | 每个DS之间有电容,CBB电容3.9NF/1000V |

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 跟电容也有一定的关系,开关管两侧电容容量有些许差别 |
