Everything about HVDC - Explained by an Engineer - Introduction Mar 25, 2026 - HVDC is powering some of the most ambitious energy projects on Earth — from interconnectors between countries to proposals linking entire continents. But why do we use DC instead of AC for these ultra-long connections? In this video, I break down how HVDC actually works — from the physics of AC vs DC, to the limitations of cables, and why effects like capacitive charging currents, the Ferranti effect, and skin effect make AC unsuitable for long-distance subsea transmission. We then dive into converter technology, explaining: How LCC (thyristor-based) systems operate How VSC (IGBT-based) systems build waveforms using modular multilevel converters (MMC) What submodules, capacitors, and valve stacks actually do Why thousands of semiconductors are used instead of just a few We`ll also compare LCC vs VSC, explore power control, black start capability, harmonics, ripple frequency, and why HVDC enables asynchronous interconnection between grids. By the end, you`ll understand: Why HVAC cables are limited to ~100 km How HVDC overcomes those limits Where each technology is used today — and what`s coming next Povezane vesti Sep 18, 2026 China to develop new-type power grids during 2026-2030 period Sep 15, 2026 The Tools That Power the People Behind the Grid Sep 15, 2026 Have your say on EirGrid`s plans for south coast offshore infrastructure Sep 13, 2026 Can Scotland`s Abundant Wind Power a Data Center Boom?
