Latest Patents

David Gellis holds a patent for a "Multi-level inverter for wireless power transmission." This patent describes controllers configured for a wireless power system and methods for such controllers and systems. The controller includes a control module that generates a first control signal with a first voltage level and a second control signal with a second voltage level. Additionally, a modulator is configured to receive a signal representative of the output current and generate carrier signals based on that output current. When a first carrier signal exceeds the first voltage level, a first gate drive signal for a first switch is activated. Similarly, when a second carrier signal surpasses the second voltage level, a second gate drive signal for a second switch is activated. This process drives an inverter to output a multi-level voltage based on the respective drive signals.
