• Sommario/riassunto: "This book provides comprehensive information on the pulsewidth modulated DC-to-DC converters for analysis and design as standalone converters and as an interconnected system. It begins with discussions of the circuits, dynamics, and control of standalone PWM converters. The second edition extends the scope of the first edition to include the dynamic analysis and system design of DC power distribution systems. The chapters in each section of the book individually underscore the issues of standalone PWM converters and collectively address the dynamics of DC power distribution systems. The authors balance theories with practical aspects of DC-to-DC power conversion based on classical linear system theory"--
