LINE FREQUENCY RIPPLE REDUCTION IN A RESONANT CONVERTER |
| 摘要 |
Systems and methods for reducing the line frequency ripple in a resonant converter are described. In some embodiments, a power supply includes a switching network; an LLC resonant tank coupled to the switching network; a rectifier coupled to the LLC resonant tank; and a control circuit coupled to the switching network and to the rectifier, where the control circuit is configured to modify an operating frequency of the switching network to reduce a line frequency ripple at an output of the rectifier. |
