Why is a high voltage measurement necessary for power efficiency measurement?

Therefore, the power efficiency measurement requires a high voltage measurement. Since WPT transfers power through coils, the transmit/receive part has a very low power factor. When the power factor is low, the phase error greatly affects the measured value, so power measurement with a low phase error is essential. Figure 5.
