有一个测试盒,但是不知道J6,J7 端口的电压是看示波器上的有效值电压还是峰值电压? M2 |& w& _- u1 _0 O另外,向高工请教一下16.1故障测试中的整流效应,标准说按照图1 的测试电路,可图一的电路好像是测不对称脉冲电压的图。When testing electronic ballasts for the rectifying effect, the circuit shown in Figure 1 is used.4 h9 f- Q/ v% q6 p8 ^ Y) P

都有对应的测试设备的,三种方法选一个买设备就是
" Y5 V: Z; B, s1 P6 {4 l c) |您好,谢谢您的指教,还有一个问题:16.1整流效应说要把整流器的阳极连接到等效电阻的中点,阴极连接到短路的灯的电极,灯的每端pin之间本来就是通的,还用短路吗?谢谢指教。 . `* ~5 k$ q* h) Q& b& V" V0 hWhen testing electronic ballasts for the rectifying effect, the circuit shown in Figure 1 is used.

灯的两pin之间是有电阻的
