Группа выше: Электробезопасность и защита цепей
Смысл: The main idea is that the increasing use of high-power direct current (DC) in home DIY solar and lighting projects creates severe fire and safety hazards because users apply AC safety logic to DC systems, which is fundamentally incorrect and dangerous.
Using direct current (DC) in home DIY projects without professional inverters and DC-specific safety components poses a significant risk of house fires and lethal shocks.
Смысл: The main idea is to debunk the absolute prohibition of using AC electronic transformers for LED strips, proving that with an anti-parallel connection, it is a safe and viable alternative, albeit with reduced luminous efficiency.
LED strips can be safely powered by AC electronic transformers using an anti-parallel connection, though they will emit less light than with a DC power supply.
Смысл: The main idea is that while alternating current won the initial battle for city electrification, high-voltage direct current is now essential for long-distance power transmission and the integration of renewable energy sources.
Once defeated by AC in the 'War of Currents,' high-voltage direct current (HVDC) is now making a comeback as the most efficient way to transmit renewable energy across vast distances and undersea cables.
