“…Not only in standard industry converters or medium voltage drives but also in traction converter systems like the Medium Frequency (MF) topology [12], [13], [14] the robustness and reliability of GDUs is essential for the system's reliability and thus availability. This is due to the high number of power switches in such systems.…”

“…In this case i?G,on,2 equals the internal gate resistor Ì?G,Ì of a typical IGBT, which is naturally the lowest possible value, and -RG,OII,I includes an external gate resistor as specified in the data sheet. Using (14) this yields a relative loss saving potential of 29 %. To ensure the introduced method is robust and will work appropriately at all working points and over the whole tem perature range, a lot of switching tests have been conducted.…”

In recent years a tendency to increase the number of semiconductor switches in power electronic systems can be observed. This changes the requirements of modern gate units, which are forced to become more simple and reliable. Nevertheless, the performance of the switches should not be affected. This paper presents a review of the state of the art for GDUs. Since existing driving methods are often far too complex and expensive for modern PE-Systems (e.g. power electronic traction transformer etc.), a new simple Dual Stage Driver GDU with fixed timing control is proposed to reduce the IGBT turn-on losses. A detailed analysis of the timing dependency of important switching characteristics is given for every operating point to verify this method.
