I try to work on TI renewable kit. To run the kit, I follow the precedure,explained in Renewable Energy Kıt GUI Overview (QSG-Renewable-Piccolo-GUI.
pdf).
I arrange jumper settings for 220V AC that is, pins 2-3 of JP7 jumper are shorted. After connecting 220 AC line to J7, LED2 led dosent light. I looked at primer AC voltage of the transformer and I measure 220AC voltage as expected between pins 1-4 of the transformer. But There is no voltage at the seconder side that is, the AC voltage between pins 5-6 of the transformer is 0V. Then, I measure the empedans of the transformer at the primary and secondary side. I measure the empedans between pins 5-6 (seconder side) as 1ohm as expected. But its not true for the empedans between pins 1-2 or pins 3-4 (primer side of the transformer) . Empadans of the pins 3-4 empadans is at megaohm level while pins 1-2 empedans cant be measured.
What is your suggestion for this problem?
