[0031] The solution of the present invention will be further described below with reference to the accompanying drawings.
[0032] see image 3 , a kind of technical scheme provided by the present invention:
[0033] An all-gallium nitride integrated secondary turn-off overcurrent protection circuit includes a blanking circuit, a delay circuit, a withstand voltage and detection circuit, a judgment circuit, an adjustable and controllable clamp circuit, and a hard turn-off bleeder circuit.
[0034] Blanking circuit and delay circuit: The same structure is used to shield the gate oscillation when the power device is turned on, and delay the overcurrent signal.
[0035] Withstand voltage and detection circuit: when the power device is turned off, it is used for high-voltage isolation between the overcurrent protection logic circuit and the bus voltage; when the power device is working, it is used to monitor the drain voltage of the power device in real time, as the basis for over...
