Abstract
A resonant circuit and a control method thereof, the resonant circuit including a plurality of resonant modules connected in parallel. The control method includes: obtaining an output current signal and an output voltage signal according to an output current and an output voltage sampled of the respective resonant module; correspondingly generating, via the respective resonant module, a first control voltage signal through a voltage loop according to a current difference between the output current and an average output current and the output voltage signal, and correspondingly generating a second control voltage signal through a current loop according to the output current signal; selecting to use one of the first or second control voltage signal according to whether the output current reaches the current limit value for controlling a switch frequency of the corresponding resonant module, thereby achieving current-sharing or current-limiting control of the respective resonant module.
