Abstract
A method for operating a light detection and ranging (LIDAR) device is provided. The method includes driving, by an LLC resonant power converter, a wireless power signal at a primary winding of a transformer disposed on a first platform. The method includes transmitting the wireless power signal across a gap separating the first platform and a second platform. The second platform is configured to rotate relative to the first platform. The method includes receiving the wireless power signal at a secondary winding of the transformer. The secondary winding is disposed on the second platform. The method includes operating, by the LLC resonant power converter at a unity gain operating point and in an open loop mode without feedback control, a device mounted on the second platform based on the secondary winding receiving the wireless power signal.
