It begins with the simple definition of a power supply and moves into the critical decision-making process of choosing from hundreds of circuit topologies to meet specific system requirements like cost and efficiency. The Art of Magnetics:

Whether you are a fresh engineering graduate or a seasoned designer, finding a single source that balances theory with practical implementation is rare. Robert "Bob" Mammano—widely recognized as the "father of the PWM controller"—distilled 40 years of industry-leading seminars into one comprehensive guide: Fundamentals of Power Supply Design

It is important to address the "PDF" search. Robert Mammano’s Fundamentals of Power Supply Design was originally published by as part of their educational series.

Details hundreds of circuit topologies and various control algorithms, including Pulse Width Modulation (PWM) methods. Specialized Sub-disciplines:

The book is structured into 13 chapters that move from fundamental definitions to advanced practical implementation:
