High-voltage side gate drive circuit resistant to power supply noise interference

A high-voltage side gate drive circuit resistant to power supply noise interference comprises a floating power supply VB-VS, a dipulse generation circuit, a high-voltage level shift circuit, a noise filter circuit containing a random detuning noise filter circuit, an RS trigger, and an output drive circuit. The random detuning noise filter circuit is connected with a common-mode noise filter circuit, and a first output end and a second output end of the common-mode noise filter circuit are connected with a first output end and a second output end of the random detuning noise filter circuit; the common-mode noise filter circuit is composed of six NAND gates and four inverters, can effectively filter power supply common-mode noise generated in the floating process of a high-voltage side power supply VB, and prevent a spurious triggering phenomenon caused by common-mode noise interference in the high-voltage side circuit; the common-mode noise filter circuit adopts a pure digital circuit and has no passive device, and the circuit is simple in structure, thus being for suitable for application to chips in a high-voltage side gate drive circuit, a half-bridge drive circuit and an intelligent power module, etc.
