摘要： An exemplary apparatus and method for using intelligent gate driver units with distributed intelligence to control antiparallel power modules or parallel-connected electrical switching devices like IGBTs is disclosed. The intelligent gate drive units use the intelligence to balance the currents of the switching devices, even in dynamic switching events. The intelligent gate driver units can use master-slave or daisy chain control structures and instantaneous or time integral differences of the currents of parallel-connected switching devices as control parameters. Instead of balancing the currents, temperature can also be balanced with the intelligent gate driver units.
摘要翻译： 公开了一种使用具有分布式智能的智能门驱动器单元来控制反并联功率模块或并联电气开关器件（例如IGBT）的示例性装置和方法。 智能门驱动单元即使在动态切换事件中也使用智能来平衡开关器件的电流。 智能栅极驱动器单元可以使用主从或菊花链控制结构以及并联开关器件电流的瞬时或时间积分差作为控制参数。 代替平衡电流，温度也可以与智能门驱动器单元平衡。
