Hi all! I'm implementing diode rectifier with AC voltage supplied from centre-tapped transformer. The diode rectifier consists of 2 diodes and will be followed by a LC filter and 10ohm resistive load. This design was built on the printed circuit board. I obtained my waveform for Primary voltage of centre-tapped transformer, voltage across diode and the current flowing through diode. But looking at the waveforms, why the waveform is not rectified nicely? what is the reason causing the circled area to occur?? Thanks very much.
