Sažetak
Step response method is a method for detection of foreign metal objects in the proximity of the transmitter coil in WPT system. It is based on a measurement of the resonant frequency of the transmitter’s LC tank. As such, it can be used on the fly, while the wireless power transfer takes place, and it should have low impact on WPT system performance. This paper discusses drawbacks of the step response method with respect to required modifications of the transmitter and receiver circuits, and also the impact it has on the DC power supply through increased inrush currents. The discussion is verified through measurements on the built prototype with implemented step response method.
