When mass electronics emerged in the 1980s, the chips were powered by DC and tended to operate at fractions of 12V, partly as a legacy of the voltages used in telecoms and in the automotive industry.
AC-DC converters are electrical circuits that transform alternating current (AC) input into direct current (DC) output. They are used in power electronic applications where the power input a 50 Hz or ...
DC motors are electric motors that are powered by direct current (DC), such as from a battery or DC power supply. Their commutation can be brushed or brushless. The speed of a brushed DC motor can be ...
