Hi, everyone!
In this circuit, the output voltage of the MB6S is 1.4 times more than the input voltage during the no-load time. Where is the problem?
Normal time: the output voltage is 12v when the load is empty, the input is not measured.
When the short circuit appears in the behind side while using, the output voltage is up to more than 19v, sometimes even more than 20v during the no-load time. And this time the input voltage is about 11v. What is this going to be?
Of the three capacitors, C2 and C3 are the electrolytic capacitors of 330uf and the resistance is 25V. C1 is the patch capacitance, the capacity and pressure are unknown. C2, C3 are all taken down and measured in a multimeter. The output voltage of the bridge in the absence of capacitance is 10v, which corresponds to the input voltage of 0.9 times. There seems to be no problem.
What went wrong, or was there no problem at all?
Please give me your comments! Thank you very much~
