Hello,
I have two relays to drive two different loads, AC input voltage is 115V RMS, 60Hz, single phase.
There are full wave rectifier circuits after out contacts of relays, respectively.
I use pn: MB6S-TP diode to full wave rectifier and my schematic is attached.
The problem is when one of the relays is on, I measure "Measurement Point" and I see not fully rectified voltage(IMG-8396, purple line on oscilloscope)
I measure fully rectified voltage on "AC_OUT2_V", approximately 1,42V(yellow line on oscilloscope).
Then when both relays are on, I measure voltage similar to IMG-8396 but peak voltage drops and I measure 1,33V on "AC_OUT2_V".
The output of full wave rectifier should be DC but, it isn't.
I will be glad if you share your comments.
Thanks,
