Latest Patents
One of Li-Chuan Tang's key patents is the "D-mode GaN transistor synchronous rectifier and power converter having the synchronous rectifier." This invention features a D-mode GaN transistor synchronous rectifier that includes a power switching module, a peak detection module, and a gate driver module. The peak detection module is designed to store energy when the negative end of the secondary side winding of the power converter is at a high voltage. The power switching module consists of a first switch and a D-mode GaN HEMT as a second switch connected in series. The energy is supplied to the module gate of the power switching module through the gate driver module, ensuring that the first switch remains turned on. Additionally, the gate driver module conducts the module gate and the module source when the positive end of the secondary side winding is at a low voltage, allowing a clamp circuit to pull the gate-source voltage of the second switch below the threshold, effectively turning it off. This synchronous rectifier replaces conventional diode rectifiers, resulting in lower conduction loss and reduced response ringing.
