The family of α-stable distributions is used as a suitable and flexible tool for the modeling of signals with impulsive nature. By using computer simulation we show the behavior of both equalizers due to impulsiveness noise influence.

Therefore, there is a need for an electronic device that can transfer electrical power efficiently from one voltage step to another to energize automotive applications. A DC-DC converter is required between the source and the delivery. Here, the paper presents a proposed DC-DC converter design that is utilized to provide a low power high voltage supply for applications in FCEV. A piece of test equipment requires a low current (0.25A), high voltage (200V) supply to be generated from a 24V battery source. Typical solutions employ a flyback converter with transformer coupling that achieved high voltage levels. Technically using (WBG) wide-bandgap - based switching device is the most approach for FCEVs applications. SiC MOSFET of high voltage 10 - 15 kV which is the best choice for high voltage applications. This research uses Psim software to simulate a flyback converter with high voltag...
