摘　　要：由于级联H桥各IGBT驱动模块存在外围电路复杂、保护功能不足且模块间信号同步性要求高等诸多问题,设计了适用于级联H桥变流器IGBT工作的驱动与保护策略电路,以主从控制器结构为基础,重点对底层FPGA控制器和IGBT驱动控制及实现方法进行了研究,并对过载保护电路、过流检测与保护电路,以及VHDL实现方案进行了详细的设计和分析。实验结果表明,本设计方案能很好地满足基于级联H桥变流器IGBT的工作要求。具有广泛的工程应用前景。In order to solve the problems of the complexity of the periphery circuit,deficiency of protection function and high requirement of signal synchronization between modules,it is necessary to design the IGBT gating and protection scheme suitable for the cascaded H-bridge converters.The controller architecture based on the master/slave configuration is presented in this paper,with the main focus on the implementation issues of the bottom FPGA controller and IGBT drivers.Besides,a specific design procedure for the over-load protection circuit,over-current detection and protection circuit with VHDL application are presented.The experimental results show that the presented scheme is capable to meet the requirement of cascaded H-bridge converter,which can be widely utilized in practical applications.
