Recently, serious safety issues related to Li-ion batteries caused due to fires or explosions in devices such as cell phones, laptops, electric vehicles, and airplanes have sparked worldwide attention. 4 Few examples include fires or explosions in Samsung Note 7, Tesla electric car battery fire, and the Boeing 787 Dreamliner battery issues, …
22.5: Direct and Indirect Band Gap Semiconductors
In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum, as in the schematic below. In an indirect band gap semiconductor, the maximum energy of the valence band occurs at
Review of Switching Concepts and Power Semiconductor Devices
In practical systems, additional energy storage elements are present to facilitate energy transfer; however, losses are part of these components and the parts of the switching devices. If we assume ideal storage elements and ideal switches, then it is conceivable to achieve 100% efficiency in the switch matrix arrangement shown in Fig. …
