Essentially my problem is this: I built a simple half-wave rectifier with some capacitive filtering, but I can't account for why my voltage is so low.
Vs is 5V amplitude, 10 Vpp, 60 Hz, sine wave. Using newer Tektronix Oscilliscopes and Signal Generators.
From my hand calcs, the output voltage should have been about 3.1V to 4.4V (the 1N4007 diode has a forward voltage of about 0.6V). Just to make sure I wasn't crazy, I confirmed this with LTSpice:
So there are a number of things bothering me here:
- Why does the input waveform look strange?
- Why is the output voltage so much lower than expected?
- Why is the ripple voltage narrower than expected?
I spent some time with the 1N4007's datasheet and played with the SigGen impedance but that didn't help and I'm not really able to answer this question in my head.
