350 V GaN Power Transistor − 20x Smaller Than Comparable Silicon
EPC announces the production release of the EPC2050, a 350 V GaN transistor with a maximum RDS(on) of 80 mΩ and a 26 A pulsed output current. The EPC2050 measures just 1.95 mm x 1.95 mm. This tiny size enables power solutions that occupy ten times less area than comparable silicon solutions. Applications benefiting from the

Figure 1. Typical B-H curve from positive saturation to negative saturation. When H is zero there exists Br which requires -Hc to return to zero. The area within the loop is core loss per cycle

What are AC Losses and why are they important? This paper discusses the physical effects and which issues must be observed by design engineers. Furthermore, an approach to determine AC losses with unmatched accuracy is being introduced. In 1892 Charles P. Steinmetz, working for General Electric presented his no
