Manufacturer:NEC Description:Calculating power assumes that the voltage and current are sampled exactly the same time. Obviously, using a single ADC with one sample-and-hold circuit makes this impossible. We can do the next best thing, however, by using an interpolated voltage value that very closely approximates what the voltage would be when the current is sampled. The principle is graphi- cally represented in Figure 1. Although current is shown here as a regular sine wave and in phase with voltage, this is not a requirement; current can have any waveform and phase relationship. |
