Latest Patents

Musil's most recent patents showcase his ingenuity in dealing with foreign object detection in wireless power systems. The first patent describes a method and apparatus for detecting the presence of conductive foreign objects in a multi-coil wireless power system. This innovative system allows for the acquisition of quality information from the wireless power receiver's resonant circuit without incurring additional costs or interrupting the power delivery to the load. By measuring the free-running coil current or voltage during a brief time window, his method ensures accuracy through the disconnection of the transmitter coil, relying on the sufficient DC-bus capacitance of the receiver.

The second patent presents a power transmitter unit that consists of a power-transmitting coil designed to wirelessly deliver power to a receiver unit. This device incorporates a resonant capacitor to create an LC circuit, enabling a specialized foreign object detection mode. In this mode, the LC circuit is short-circuited, facilitating the measurement of coil current signals. The controller processes these signals to determine the circuit's resistance, signaling the presence of a foreign object when the resistance exceeds a predefined threshold.
