栅极驱动电路和栅极驱动器
摘要：
本发明提供一种栅极驱动电路和栅极驱动器，包括：信号控制模块、处理模块和第一调整模块；处理模块分别与信号控制模块、第一调整模块连接，信号控制模块还与第一调整模块连接；信号控制模块，用于向处理模块和第一调整模块输出控制信号；处理模块和第一调整模块，用于根据控制信号，控制栅极驱动电路的PU信号点的电压维持为预设电压，栅极驱动电路的PU信号点为处理模块和第一调整模块的连接点。本发明提供的栅极驱动电路能够使得其中的PU信号点的电压维持为预设电压，解决了栅极驱动电路中晶体管打开，泄露PU点电压的问题。
摘要（英）：

The invention provides a gate driving circuit and a gate driver. The gate driving circuit comprises a signal control module, a processing module and a first adjusting module; the processing module isconnected with the signal control module and the first adjusting module, and the signal control module is connected with the first adjusting module; the signal control module outputs a control signalto the processing module and the first adjusting module; and the processing module and first adjusting module keeps the voltage of a PU signal point, where the processing module is connected with thefirst adjusting module, of the gate driving circuit in a preset voltage according to the control signal. The voltage of the PU signal point can be kept in the preset voltage, the problem that the voltage of the PU point is leaked when a transition in the gate driving circuit is switched on.
