Manufacturers of power semiconductors and modules intend to rate the maximum junction temperature up to 200°C. This results in higher temperatures at other components of the inverter system as well. In this paper, it is presented a method to identify thermal constraints in an inverter design by combining analytical and numerical analysis of the thermal spreading. Furthermore, an overview of the thermal...
Gate units of todaypsilas converters are in most cases voltage sources charging the input capacitance with a fixed gate resistor. Consequently, there is hardly no possibility to adapt quickly the gate unit to different semiconductor devices. During operation, there is no adaption process to adjust the switching transients to their actual optimum. The possibilities to implement new features or to adapt...
Gate units of todaypsilas converters are in most cases voltage sources charging the input capacitance with a fixed gate resistor. In some publications, fixed current sources are implemented to support the charging process with a supplementary gate current. These solutions are implemented in an analog way and are designed and respectively optimized for fixed parameters and devices. During operation,...
