METHOD AND DEVICE FOR SWITCHING ON AND OFF POWER SEMICONDUCTORS, ESPECIALLY FOR THE TORQUE-VARIABLE OPERATION OF AN ASYNCHRONOUS MACHINE, FOR OPERATING AN IGNITION SYSTEM FOR SPARK IGNITION ENGINES, AND SWITCHED-MODE POWER SUPPLY |
摘要 |
The invention relates to a method and to a device for switching on and off power semiconductors, especially IGBTs or power MOS-FETs with inductive load, such as are preferably used for the torque-variable operation of asynchronous machines, in ignition systems for spark ignition engines, in switched-mode power supplies or in power factor controllers. A voltage (UCE; UDS) dropping across the power semiconductor and a current (IC; ID) flowing through the power semiconductor are detected and their temporal progression during a switching operation is controlled. The temporal progression of the voltage (UCE; UDS) and the temporal progression of the current (IC; ID) are substantially controlled in a time-delayed manner. |
