Abstract
A method and apparatus for controlling a converter are provided. In the method and apparatus, a controller determines a difference between an on-time and an off-time of a command signal representative of a switching signal of the converter. The controller generates a control signal based on the difference between the on-time and the off-time and compensates a first signal representative of a current of a resonant tank of the converter using the control signal. The controller generates the switching signal based on the compensated first signal.
