Power electronics, of speeds was required. Power electronics has removed that restriction by making it possible to operate AC and DC machines over a large range of speeds by varying the frequency or the voltage, or both, of its supply. In essence the methods are

Not only have very low-power CMOS (complementary metal oxide-semiconductor, a type of FET) ICs have become reliable and cheap, but also devices such as HEXFETs and VMOS FETs have replaced many types of power bipolar devices, and semiconductor memories are no more than huge arrays of MOSFETs.
