Before diving into the book's contents, it's helpful to understand the technology it covers. High Voltage Direct Current (HVDC) transmission involves converting alternating current (AC) to direct current (DC) for efficient, long-distance power transfer, and then converting it back to AC for integration into the grid. HVDC systems offer several key advantages over traditional AC lines, including:
HVDC links allow countries or regions with completely different grid frequencies (e.g., 50 Hz and 60 Hz) to trade electricity smoothly. Padiyar’s work is noted for its rigorous treatment
Most engineering universities provide free institutional access to digital catalogs, e-book platforms, or physical copies via library networks.
During this overlap period, three valves conduct simultaneously, momentarily dropping the DC output voltage. Padiyar provides the foundational equations to calculate this voltage drop as a function of the DC current ( Idcap I sub d ) and commutation reactance ( Xccap X sub c Inverter Equations and Extinction Angle
However, some readers offer practical advice for those new to the subject. A few note that the book can be "a little advanced for UG" (undergraduate) students, as it assumes "some prerequisites and more common sense of basics". This feedback suggests that while the book is an excellent resource, beginners might benefit from first having a solid foundation in basic power system analysis or consulting more introductory texts before diving in.

and Constant DC Voltage (CDCV) control at the inverter station.
Work through the numerical example on page 312 about the inverter commutation failure. That single calculation explains 80% of the blackouts in Brazil and India over the last decade.
So, find the PDF if you must. But print out Chapter 8 (Control of HVDC). Staple it to your wall. Because when the AC voltage dips and the inverter is about to commutation fail, you won’t have time to Google it—you’ll need Padiyar in your bones.
