The invention discloses an IGBT (Insulated Gate Bipolar Translator) driving system of a new energy electric vehicle. The IGBT driving system comprises a high-voltage flyback power supply module, an LDO (Low Dropout Regulator) circuit module, an ASC logic judgment circuit, an IGBT driving circuit module, a high-voltage flyback power supply module for taking power from a high-voltage battery pack of the whole vehicle, an IGBT driving chip for supplying power to the LDO circuit module after performing level conversion on high-voltage power, the LDO circuit module is connected with the ASC logic judgment circuit; the ASC logic judgment circuit is connected with the IGBT driving chip, and the ASC logic judgment circuit generates an ASC enable signal to enable the IGBT driving chip to enter an ASC mode. According to the invention, when the power supply of the high-voltage battery pack accidentally fails, the IGBT driving system can still enter the safety state of ASC active short circuit.

    本发明公开了一种新能源电动车的IGBT驱动系统,包括高压反激电源模块、LDO电路模块、ASC逻辑判断电路、IGBT驱动电路模块,从整车高压电池包取电的高压反激电源模块,将高压电进行电平转换后供电给所述LDO电路模块、所述IGBT驱动芯片;LDO电路模块与ASC逻辑判断电路连接;ASC逻辑判断电路与IGBT驱动芯片连接,ASC逻辑判断电路产生ASC使能信号使IGBT驱动芯片进入ASC模式。本发明可实现当高压电池包电源意外失效,IGBT驱动系统仍然可以进入ASC主动短路的安全状态。
