Synonyms: ripple-voltage ripple-current

Subtag of power-supply

Anything about ripple in power supplies and the techniques to reduce its magnitude or its influence on the powered circuits.

The ripple is a residue of line AC and/or of the switching waveform (for SMPS) superimposed to the output DC of a power supply. Ripple is a phenomenon due to the unavoidable imperfection of the conversion process from AC to DC or from DC to DC.

Ripple on Wikipedia.

Q&A Flyback Converter - Output Ripple

I am eager to create a flyback converter for driving the high side MOSFET. Here is a snapshot of my work so far: 555 timer starts with generating ~100kHz 12V signal on Q1. Q2 is monitoring the v...
