More Information
Summary: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.
