Potential of digital gate units in high power appliations

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 the units for a different device are related to time and effort. Therefore, in this paper the idea of a digital gate unit is explained and presented.
