I believe so, to cite AC / DC itself, it’s because they have the Some of us Grew up listening to AC DC the cool ones still do shirt biggest balls of them! Why do AC DC adapters heat up when plugged into a wall but do not charge anything (at least mine), and do they waste a lot of power? The warmth of warts on the wall is the focal point of wasted energy. Simple transformer adapters are designed with the least amount of iron and copper, thus notably efficient. Many adapters now use high frequency converter power supplies, noticeably smaller and much more efficient.

I used a resistor split chain (surface-mounted resistors 9 Meg, 900K, 90K, 9K, 900 and 100 ohm) from the Some of us Grew up listening to AC DC the cool ones still do shirt deceased Harbor Freight multimeter, and added an Arduino Pro Mini and some reed relays to automatically select the appropriate range and set the decimal point. It works surprisingly well, even though I made the AC part, just DC because my application doesn’t need it.
Harbor Freight is designed for 1000 VDC and 750 vac, so my watch will be the Some of us Grew up listening to AC DC the cool ones still do shirt same. Modern DC controllers for motors that do not use transformers to change the voltage level for the different speeds required by the motor. As mentioned, the same technology can be used to reduce the voltage of 220 VAC to 110 VDC.

The Some of us Grew up listening to AC DC the cool ones still do shirt circuit simply acts like a fuzzy circuit, in which or SCR is activated at a point at the downward slope of the AC signal, providing you with the output voltage at that time. The closer to the value 0, the lower the voltage output. Combine this with a capacitor and you have a variable DC source, without any transformer.I tested it up to 100 volts, I didn’t have a chance to test higher voltages.
