Power Line Disturbances and Their Effect on Computer Design and Performance by

Vincent Roland Proper site wiring, adequate grounding, and use of isolation devices help assure satisfactory performance. When we plug something into an electrical outlet we are connecting it to a voltage that alternates between positive and negative values 50 or 60 times per second, depending on the country. This voltage may be subject to random noise and to large, unpredictable, sudden fluctuations as the utility company supplying us with electric power experiences...

Designing magnetic components tor operation at 200 kHz requires careful consideration of the properties ot materials beyond any normally required at much lower frequencies. Each of the major magnetic components in the 65000A Series presented a different set of problems requiring resolution Our goals were lo develop components small in size, design to meel the most stringent of European safety specifications, and allow for the possibility of semiautomated manufacturing to reduce manufacturing...
