High reliability and system lifetimes in the range of 30 years are essential for renewable energy systems such as photovoltaic power plants to minimise costs for the generated electric energy. At the same time such systems are used in regions with high solar irradiance and also harsh environmental conditions. Therefore, designs for photovoltaic inverters need to meet not only the key design criteria of high conversion efficiency but also need to be very robust and at the same time meet challenging cost targets. In this dissertation aspects concerning the lifetime and reliability of power semiconductors in photovoltaic central inverters are investigated. On key topic of the dissertation is the measurement of the voltage dependent failure rate due to cosmic radiation induced single-event-burnout of SiC and Si power semiconductors. The second topic is the development of a system level simulation to quantify the stress on the power semiconductors in a PV central inverters in various regions of the world. Further topics are the investigation of improved control concepts for the cooling system of PV central inverters and the monitoring of IGBT temperatures during converter operation.

Download Fault Diagnosis for Robust Inverter Power Drives Book in PDF, Epub and Kindle

This book deals with the concept that the specification of a power component needs a life expectancy associated with other important factors, to allow the appropriate component selection when designing robust and reliable systems. An analysis of the fundamental physics of aging in power drive components and the markers that diagnose the process towards failure is presented to illustrate to the reader state-of-the-art approaches to increase reliability. Amongst the many factors playing an important role in designing a robust power drive, the main factor deals with how long the power drive will last at the conditions in which it will be operating. In particular, the book looks at invertor power drive reliability and diagnosis; power semiconductors, SiC, GaN, MOSFETs and IGBTs; DC-link capacitors; embedded fault diagnosis and prognosis; fault tolerance strategies for power convertors; motor diagnostics and protection using invertor capabilities; battery storage; prognostics with a particular application to a battery.

This book provides the most up-to-date information on hybrid solar cell and solar thermal collectors, which are commonly referred to as Photovoltaic/Thermal (PV/T) systems. PV/T systems convert solar radiation into thermal and electrical energy to produce electricity, utilize more of the solar spectrum, and save space by combining the two structures to cover lesser area than two systems separately. Research in this area is growing rapidly and is highlighted within this book. The most current methods and techniques available to aid in overall efficiency, reduce cost and improve modeling and system maintenance are all covered. In-depth chapters present the background and basic principles of the technology along with a detailed review of the most current literature. Moreover, the book details design criteria for PV/T systems including residential, commercial, and industrial applications. Provides an objective and decisive source for the supporters of green and renewable source of energy Discusses and evaluates state-of-the-art PV/T system designs Proposes and recommends potential designs for future research on this topic

Solar power has become big business, with $131 billion invested in 2018, up from just $11.2 billion in 2004 but down from $171 billion in 2017 as unit costs fell. New installed capacity grew from 1.1GW in 2004 to about 107GW in 2018, a steady rise as solar begins to compete with fossil fuels on cost and to be built in nearly every country.This is a book for the solar workers of the future, a business book for those without a business or economics background and those simply curious about major shifts happening in the world energy economy. Key financial, economic and technical concepts are interspersed with the history of the first decade of cheap solar power, and the author's experience of being part of a successful startup in the clean energy sector.Related Link(s)

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.
