Converting DC voltage is unlike AC with transformers not easy or practical.

Converting DC voltage is unlike AC with transformers not easy or practical.
- makomk 7y agoVery few AC-powered devices even use traditional transformers anymore. Mostly they have some kind of switch-mode power supply which immediately rectifies the AC to DC. (Better and higher-power supplies have complicated active power factor correction circuits to do this.) Then they convert that high-voltage DC to low-voltage DC.
