| Abstract |
In nowadays designs for industrial drives or renewably energy systems many high power inverters in power level up to 1 MW or even beyond that rating are designed using IGBT modules in the voltage class of 1200 V or 1700 V. The design of such an inverter imposes a significant challenge to the engineering team since currents in the order of several thousands ampere have to be switched within fractions of a microsecond. Switching tests using a parallel configuration of three modules controlled by a modular driver system consisting of a central driver and local boosters are presented. Thermal design aspects for the power circuit as well as for the driver are investigated considering the increased operating temperature of the IGBTs of 150C. |
