Title:
CONTROL OF ACTIVE RECTIFICATION IN WIRELESS POWER SYSTEM
Document Type and Number:
Japanese Patent JP2023053372
Kind Code:
A
Abstract:
To provide suitable control of active rectification of a radio power system.SOLUTION: Described herein are active rectification methods and systems for a rectifier of a wireless power system. Exemplary methods can include detecting, by a zero-crossing detector, one or more zero-crossings of a current at an input of the rectifier and determining a first delay time based on at least one wireless power system parameter and the zero-crossings. The methods can include: generating first and second control signals for first and second switches of the rectifier, respectively, based on the first delay time; inserting a first dead time between the first control signal and the second control signal; and providing the first and second control signals to the first and second switches, respectively.SELECTED DRAWING: Figure 3A
