Latest Patents

Zhang's latest patents focus on an Adaptive Synchronous Rectifier Sensing Deglitch method, which offers a sophisticated controller for managing the on and off periods of a synchronous rectifier switch transistor in switching power converters. This novel method encompasses a two-step approach: the first step involves monitoring an unfiltered signal to determine whether the SR switch transistor should be activated during the initial phase of the power switch cycle. The second step requires overseeing a filtered signal to regulate the operation of the SR switch in the latter phase of the power switch cycle. This dual-step monitoring is crucial for optimizing performance while maintaining system reliability.

The second patent of the same title enhances the functionality of the synchronous rectifier controller. It adeptly enables and disables a deglitch filter, allowing for rapid switching of the synchronous rectifier switch during optimal periods, thus improving overall efficiency. In times when the deglitch filter is not disabled, the system is effectively protected, showcasing the balance between performance and safety in power conversion applications.
