Produktbeschreibung
In high power, high voltage electronics systems, a strategy tomanage short timescale energy imbalances is fundamental to thesystem reliability. Without a theoretical framework, harmful localconvergence of energy can affect the dynamic process oftransformation, transmission, and storage which create anunreliable system. With an original approach that encourages understanding of bothmacroscopic and microscopic factors, the authors offer a solution.They demonstrate the essential theory and methodology for thedesign, modeling and prototyping of modern power electronicsconverters to create highly effective systems. Current applicationssuch as renewable energy systems and hybrid electric vehicles arediscussed in detail by the authors. Key features: * offers a logical guide that is widely applicable to powerelectronics across power supplies, renewable energy systems, andmany other areas * analyses the short-scale (nano-micro second) transientphenomena and the transient processes in nearly all majortimescales, from device switching processes at the nanoscale level,to thermal and mechanical processes at second level * explores transient causes and shows how to correct them bychanging the control algorithm or peripheral circuit * includes two case studies on power electronics in hybridelectric vehicles and renewable energy systems Practitioners in major power electronic companies will benefitfrom this reference, especially design engineers aiming for optimalsystem performance. It will also be of value to faculty staff andgraduate students specializing in power electronics withinacademia.
