In power electronics, as found, for example, in drive technology, IGBTs are frequently used for high voltage and high current switching. These power transistors are voltage controlled and produce their main losses during switching. To minimize the switching losses, it is desirable to have short switching times. However, fast switching simultaneously conceals the danger of high voltage transients, which could possibly affect or even damage the processor logic. Hence, gate drivers that supply the IGBTs with the appropriate gate signals perform the function of providing short-circuit protection and influence the switching speed. However, in the selection of the gate driver, certain characteristics are critical…
