This book is aimed at people who want to understand how AC inverter drives work and how they are used in industry. This book is much more about the practical design and application of drives than about the mathematical principles behind them. 
 The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The detailed electronics of DC and AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection. 
 An important part of the book gives details of the features and functions often found in AC drives, and gives practical advice on how and where to use these. A wide range of drive applications are described from fresh water pumping to baggage handling systems. The practical problems of using AC drives in industry are presented, and together with the application and function descriptions should prove useful and informative. 
 The mathematics is kept to an essential minimum. Some basic understanding of mechanical and electrical theory is presumed, and a basic knowledge of single and three phase AC systems would be useful. 
 Anyone who uses or installs drives, or is just interested in how these powerful electronic products operate and control modern industry will find this book fascinating and informative.

This paper examines the impact of the recent banking crises in Europe and Central Asia on households' incomes and consumption patterns. The analysis is based on the 2010 wave of the Life in Transition Survey, which covers 12,704 households in eleven countries that experienced a banking crisis between 2008 and 2011. It finds that households in middle-income crisis countries are more than twice as likely to be hit by an income shock as households in high-income crisis countries. The labor market channel is the predominant source of income shocks, with wage reductions more widespread than job-losses. In reaction to income shocks, households reallocate spending from non-essential goods to staple foods. Reductions in staple-food consumption are, however, prevalent among low-income households. The paper examines potential crisis mitigators and finds that at the macro level a flexible monetary regime is associated with fewer cutbacks in household consumption. At the meso level, it finds no evidence that foreign bank ownership amplified the transmission of banking crises to households in Europe. With respect to micro-level mitigators, the analysis finds that diversified income sources as well as stocks of non-financial and financial assets help households to cushion income shocks. Access to informal and formal credit also mitigates the impact of income shocks on household consumption, with the former especially important in middle-income countries.
