Hello,
I'm revising this documents of a company that providing a power electronics experiments board for our electronics labs.
I'm wondering about the measured currents in a half controlled rectifier. As the output current is positive but the currents measured at the lower sides of the thyristor or diode branches are negative.
Here are the oscilloscope signals and the on-book question/answer part.
1. Circuit:
2. Wiring with oscilloscope measuring points:
3. Their measured signals:
4. Q/A, but I didn't understand the answer quite well .. hope anyone explain it more to me:
