Digital Signal Processing in Power Electronics Control Circuits, 2e

Digital Signal Processing in Power Electronics Control Circuits discusses signal processing, starting from analog signal acquisition through conversion to digital form, methods of filtration and separation, and ending with pulse control of output power transistors. The book is focused on two applications for the considered methods of digital signal processing: a three-phase shunt active power filter and a digital class-D audio power amplifier. The book bridges the gap between power electronics and digital signal processing.

Many control algorithms and circuits for power electronics in the current literature are described using analog transmittances. This may not always be acceptable, especially if half of the sampling frequencies and half of the power transistor switching frequencies are close to the band of interest. Therefore, in this book, a digital circuit is treated as a digital circuit with its own peculiar characteristics, rather than an analog circuit. This helps to avoid errors and instability.

This edition includes a new chapter dealing with selected problems for the simulation of power electronics systems together with digital control circuits. The book includes numerous examples using MATLAB.
