The output of the coil must be passed through an integrator circuit to obtain the current waveform.
For three-phase meters that measure both voltage and current waveforms, the data is 6-8 times as much.
Three current waveforms are produced that are equal in magnitude and 120 out of phase to each other.
The current and voltage waveforms in an ideal converter can be seen in Figure 3.
D is a function of the geometry and is independent of the current waveforms.
The current waveform can become quite complex, depending on the type of load and its interaction with other components of the system.
Fig. 5.9(a) shows typical current waveforms at low and high speeds.
(5.28) for the rectangular current waveform using a graphical method.
A typical current waveform for one excitation interval is illustrated in Fig. 5.18.
Non-linear loads change the shape of the current waveform from a sine wave to some other form.
