In this paper, the marine predator algorithm (MPA) is proposed for solving transcendental nonlinear equations in a selective harmonic elimination technique using multilevel inverter (MLI). It proved its suitability and supremacy over other (SHE) techniques used recent research as it has good precision, high probability of convergence, improving quality output voltage. The optimum values switchi...

Phase-Shifted Full Bridge (PSFB) topology in its four-diode variant is the choice with lowest part count applications that demand high power, voltage, and galvanic isolation, such as Electric Vehicle (EV) chargers. Even though prevalent power electronics applications, no single, unified analytical model has been proposed for design process of PSFB converters. As a result, engineers must rely on...

One of the key advantage of SiC power devices over their Si counterparts is their ability to operate at higher temperature (in theory up to 1000 K for a 1000 V-rated SiC device as compared to less that 500 K for a comparable Si device [1]). Practical tests have already demonstrated operation at elevated temperature. For example, in [2], SiC JFET and diode operate at 450°C (723 K) ambient temper...

Insertion of a de-dc converter between the automobile battery and electrical loads is proposed. This would allow gradual conversion to higher battery voltage, regulation of de distribution voltage, and multiple distribution voltage levels. Switching loss arising from parasitic inductances is a serious problem in this application. The nonlinear resonant switch can remove this source of loss, ach...
