To illustrate the book's practical value, consider a common query: “My Flyback supply whines under load.”
According to Basso’s methodology (Chapter 8 in the PDF):
Without Basso’s analytical framework, engineers typically increase output capacitance (costly) or adjust the compensation pot randomly (ineffective). With the book, the solution is systematic. To illustrate the book's practical value, consider a
Before diving in, understand that this is not a beginner book on power electronics.
Basso is a huge proponent of the Frequency Response Analyzer (FRA) , also known as a network analyzer. He dedicates an entire chapter to: This section is priceless for practicing engineers
This section is priceless for practicing engineers. He explains common measurement traps: probe ground loops, injection level (the signal must be small enough to stay in the linear region), and high-frequency roll-off due to parasitic capacitance.
This is where the book shines. Many engineers fear the mathematical derivation of transfer functions. Basso introduces the Facts (Fairchild Automated Control & Thermal Simulation) method and the PWM switch model. He breaks the switching cell (active switch + diode) into a 3-terminal device, allowing linear analysis of a non-linear converter. You will learn to derive control-to-output transfer functions for: the error amplifier
This is Basso’s signature contribution to the field.
This is where the book shines. Switching converters (Buck, Boost, Buck-Boost, Flyback) introduce a Pulse-Width Modulator (PWM) and an LC filter into the loop—both of which add significant phase lag.
Basso systematically covers:
Basso starts with the fundamentals: negative feedback, the error amplifier, and the PWM block. He uniquely emphasizes why stability in the time domain (ringing, overshoot) is directly visible in the frequency domain (gain and phase margins). He famously correlates poor phase margin (less than 45°) to an oscillatory step load response.
