摘要
针对IGBT驱动电路复杂且保护功能不尽完善的问题,设计了一个基于2SC0108T的即插即用型IGBT驱动器,以及相应的前级驱动电路、后级功率驱动电路和故障报警电路。该驱动器具有直接模式和半桥模式、驱动信号硬件互锁、硬件死区时间可调节、IGBT过流及短路保护、驱动电源过欠压监控和易于安装的特点。结合英飞凌EconoDUAL3封装IGBT模块,完成了即插即用型IGBT驱动器的硬件设计及调试,有效减小了双绞线传输方式寄生电容及寄生电感的影响。
Aiming at the problems of IGBT drive circuity complexity and indequate protection, a plug-and-play IGBT driver is designed based on the 2SC0108T, and the primary side and secondary, side drive circuitry and failure alarm circuitry are designed. Two modes including direct mode and half-bridge mode are available. Drive signals are interlocked by hardware and the dead time is adjustable. It possesses the functions of over-current and short-circuit protection, low-voltage and over-voltage monitoring as well as easily Installation. Based on the EconoDUAL3 IGBT module, the hardware of the plug-and-play driver is designed and the functions are tested. It effectively reduces the impact of parasitic inductance and capacitance exists in the twisted pair transmission.
