Latest Patents
Among his latest innovations is a resonant converter and driving method that includes a first switch on the primary side and a second switch coupled to the first switch. This design features a first synchronous rectification switch on the secondary side, which conducts according to the switching operation of the first switch. Additionally, a second synchronous rectification switch is included, which operates based on the second switch's actions. The switch control circuit is designed to detect the waveform of the voltage at one end of the synchronous rectification switches and to control their conduction duration based on the determined operating region.
Another notable patent by Baek is also related to a resonant converter and driving method. This invention includes a synchronization rectification switch on the secondary side that conducts during a conduction period in response to the first switch's operation. The switch control circuit determines the operating region of the resonant converter to be below resonance by comparing the conduction period with the on period of the first switch.
