Abstract
(EN)
The present application belongs to the technical field of electronic circuits, and provides a resonant converter. The resonant converter comprises an input end, an output end, a first switch, a second switch, a third switch, a fourth switch, a frequency controller, a resonant capacitor, a first transformer, a second transformer and a feedback circuit, wherein the input end is connected to an external power supply; the output end is connected to an external load; the frequency controller is located on secondary sides of the first transformer and the second transformer; and the frequency controller is used to output a first control signal for controlling the first switch to act, a second control signal for controlling the second switch to act, a third control signal for controlling the third switch to act, and a fourth control signal for controlling the fourth switch to act. The present application can effectively reduce the switching loss of a primary side, such that the resonant converter can work at a high variable frequency.
