Of the remainder the most numerous ICs are analogue-to-digital (and digital-to-analogue) converters and voltage regulators. All of these types togeth

Algebraisch irrationale Integranden,s driven by these were such that the power delivered was low, just as well in view of their low efficiencies. High efficiencies are vital for power amplifiers, not because of the cost of the wasted power itself, but because it produces heat that must be removed, causing inefficient amplifiers not on

A knowledge of elementary magnetism and electromagnetism is fundamental for studying electrical machines and transformers. We shall accordingly look at some basic magnetic phenom

AC machines are more widely used than DC machines, but in certain applications DC machines used to be preferred, especially in traction and whenever speed control over a wide range was desired. With the development of high-power semico

AC generators began to be used for the same purpose and the two varieties of electricity supply coexisted for a time, with the advantage perhaps lying with DC generation. The invention by Tesla of the induction motor in 1887 altered the balance d

They range in size from multi-tonne, multi-MVA transformers in electricity distribution systems to 1VA, PCB-mounted transformers for portable instruments. Besides their high efficiencies, they are also notable for their reliability and freedom from t

Erratum to: Berichtigungen zum I. Band,otors running from the 240V supply are among the commonest in domestic use. All induction motors are cheap, reliable, rugged, lightweight and reasonably efficient; in fact large (> 1 MW) induction motors have efficiencies of up to 98%. Their biggest drawback hitherto has been their small range of op
