I am working on a project in which I am trying to measure current from a current transducer (SCT 013-030). I want to convert the output to VDC and connect it to a smoothing capacitor and load resistor. However, the bridge rectifier that I currently have to use (DF005M) appears to be a half bridge, not a full bridge rectifier.
I am seeking some guidance in how to best verify what type of bridge rectifier I have? Because the output signal of the CT is so small, I used a function generator to simulate a stronger input signal (60Hz, 20Vpp sin wave). I connected that input wave to the two '~' pins of the DF005M rectifier. When I connect the '+' pin to the purple channel of my oscilloscope, I understandably get only the positive parts of the wave. However, what confuses me is that when I connect the yellow channel to the '-' pin, I only read the negative parts of the wave.
It was my understanding that a full bridge rectifier inverts the negative parts of the wave. Thus, I am confused as to why a negative signal is even getting through in the first place...
Any guidance in properly implementing teh DF005M (or verifying the need for a different rectifier) would be much appreciated! I have searched online for customer reviews for the DF005M glass passivated bridge rectifier, but have not found any that discuss how to properly implement it. I can't even find manufacturer's resources that provide the internal circuit diagram for the component.
