Latest Patents

Trillion Q Zheng holds a patent for a groundbreaking invention titled "Power MOSFET active gate drive based on negative feedback mechanism." This invention introduces a negative feedback mechanism into the gate drive, proposing a negative feedback active gate drive (NFAGD) for silicon carbide (SiC) and gallium nitride (GaN) semiconductor devices. The NFAGD is designed to fully utilize the high switching-speed capability of these devices in a phase-leg configuration. The invention incorporates an auxiliary P-channel MOSFET to construct a negative feedback control mechanism. This mechanism allows the drive to automatically attenuate disturbances from the complementary device of the phase-leg. The NFAGD features a simple structure that can be realized using a push-pull drive circuit, a drive resistor, an auxiliary MOSFET, and an auxiliary capacitor, without the need for additional logical circuits. Functionally, it can automatically suppress the induced gate-source voltage, ensuring stable gate voltage during high-speed switching operations without sacrificing the switching speed of the MOSFET.
