Latest Patents
One of Fischer's latest patents is focused on foreign object detection using combined inductive and thermal sensing. This innovative method allows for the detection of foreign metal objects near inductive wireless power transfer systems. The sensing system utilizes both inductive and thermal effects to identify the presence of an object. A sense element within the system changes its electrical characteristics in response to the object, while a mediating heat-sensitive material varies its properties based on temperature changes. This material is heated by the foreign object when exposed to a magnetic field generated by the wireless power transfer system. A controller measures the electrical characteristics to determine the presence of the object.
Another significant patent by Fischer involves active harmonics cancellation. This system includes a wireless charging apparatus that features a wireless-power transfer circuit. The circuit comprises a wireless-power transfer coil designed to generate or couple to a magnetic field for power transfer. Additionally, it includes a power converter circuit and a signal generation circuit that injects a signal into the wireless-power transfer circuit. This innovative approach helps to improve the efficiency of wireless power systems.
