Electrical machinery and power converters are the two main parts of any electrical energy conversion system. Electrical machines are used for achieving power conversion of electrical energy into mechanical energy and vice versa. Power conversion is done with the help of a power converter. The primary function of a power converter is to convert alternating current (AC) into direct current (DC) and vice versa. It is also used to change the voltage or frequency of the current. Electrical machines use electrical energy to function. They convert mechanical energy to electrical energy or vice versa. Motors, transformers, and generators are the three primary categories of electrical machines. An electric vehicle is a type of electrical machine in which a power converter converts electrical energy stored in batteries to mechanical energy that propels the electric vehicle. This book outlines the applications of power conversion and electrical machinery in detail. Coherent flow of topics, student-friendly language and extensive use of examples make it an invaluable source of knowledge.
