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 Apr 8, 2026 The Grid Doesn`t Need More Power Plants (It Needs This) Apr 8, 2026 ERCOT Distribution Awareness Platform Apr 2, 2026 China`s retired EV batteries now light villages, store solar power and charge new cars 30 Mar 2026 The Energy Future of Switzerland Explained 28 Mar 2026 Switzerland Built An Underground Power Plant By Hollowing Out An Entire Mountain Mar 27, 2026 Georgia Tech Lead BESS - Energy Availability at Any Time Mar 25, 2026 Everything about HVDC - Explained by an Engineer - Introduction Mar 23, 2026 Electrical grid at increasing risk of blackouts due to surging demand Mar 19, 2026 The Future of Utilities: Rising Demand, AI Impact, and Lessons from the Iberian Blackout Mar 17, 2026 Powering through the storm  |
