Hi, I'm new here and know very little about electronics. I want to build a 36v battery charger in the future.
One basic question. I recently wrapped the secondary part of a transformer to put out a voltage near 40volts. After the bridge rectifier, the voltage is about 39 volts. I have 3 12 volt batteries wired in series, fully charged and showing just below 40 volts. Why is it when I connect the power to the battery that I hear electrolysis start to happen? I thought that if the output voltage is lower than the input voltage of the battery pack then the battery shouldn't accept any power.
That's my question for now. Later I want to know about the regulator part of the charger. Any good tutorials out there? thanks!
oh, Is phasing the primary to secondary important on the tranformer?
