... These transistors are typically employed in Marx generators where it is desired to generate pulses of high voltage lasting only nanoseconds so that the signal-to-noise ratio of optoelectronic receivers can be improved [1]. They can have open-base or shorted-base connections leading to different breakdown voltages [2]. A key feature of avalanche transistor operation is the negative resistance apparent in the current-voltage (I-V) characteristics. ...

... Using the same principle, auxiliary inductors can also be employed in modified DAB/DAB3 converters, helping to cover the ZVS region to the entire operating range. In [241], a 0.46μH inductor and a 62.1μH inductor are added between the two middle nodes, respectively, in a DAB converter with a Ttype full bridge. In [242], a 70μH inductor and a 40μH magnetizing inductance are utilized in a DAB converter with a half bridge and a T-type full bridge. ...
