Before diving into the content, it is crucial to understand the author. Prof. K. R. Padiyar is a revered academician and former professor at the Indian Institute of Science (IISc), Bangalore. He is also the author of another legendary text, "Power System Dynamics: Stability and Control." You will find links on websites such as Academia
Padiyar’s strength lies in translating complex mathematical models into physical intuition. His work on HVDC is particularly respected because he was writing about voltage source converters (VSC) and multi-terminal DC grids long before they became industry buzzwords. When you search for the PDF of his HVDC book, you are essentially seeking a masterclass from one of the greatest living minds in power systems.
