20080278977 | Method for operating a converter circuit, and device for carrying out the method - A method for operating a converter circuit is specified with the converter circuit having a converter unit with a multiplicity of controllable power semiconductor switches and having an energy storage circuit formed by two series-connected capacitors, in which the controllable power semiconductor switches are controlled by means of a control signal formed from a hysteresis signal vector (x), and the hysteresis signal vector (x) is formed from a difference-phase connection current vector (Δi | 11-13-2008 |
20120098577 | GATE DRIVER UNIT FOR ELECTRICAL SWITCHING DEVICE - 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. | 04-26-2012 |
