A power converter controller includes an input sense circuit to receive an input sense signal representative of an input of a power converter. A zero-crossing detector is coupled to the input sense circuit to be responsive to the input sense signal falling below a first zero-crossing threshold ...
interfere with other electronic systems through what is calledelectromagnetic interference (EMI). As illustrated in Figure 1, a simple wire may be used to sense AC electric fields using theaudio detector circuit, explained in an earlier project chapter, to detect ACvoltagesin the audio frequencies....

If an AC circuitincludes only resistors(i.e., no inductors or capacitors—much more about them later),current and voltageare alwaysin phase, meaning that their amplitudes vary in perfect synchronization. We can directly apply Ohm’s law to circuits such as this: the current through a resi...
